What is the surface area of the cylinder in terms of pi? The diagram is not drawn to scale.
The solution is, 308π in² is the surface area of the cylinder in terms of pi.
What is surface area?Surface area is the amount of space covering the outside of a three-dimensional shape. The surface area of a solid object is a measure of the total area that the surface of the object occupies.
here, we have,
from the given diagram , we get,
the cylinder has,
radius = r = 7
height = h = 15
we know that,
Surface Area = 2πr² + 2πrh
so, we get,
r = 7
h = 15
substituting the values, we get,
Surface Area
= 2π(7)² + 2π(7)(15)
= 308π in²²
Answer: 308π in²
Hence, The solution is, 308π in² is the surface area of the cylinder in terms of pi.

One of the angles of a parallelogram is equal to 40°. Find the rest of the angles.
The angles of parallelogram are 40°, 140°, 40°, 140°.
What is parallelogram?
A parallelogram is a type of quadrilateral. It is a two-dimensional figure with four sides. The most important properties of a parallelogram are that the opposite sides are parallel and congruent and the opposite angles are also equal.
For the given situation,
One angle of parallelogram = 40°
Let the unknown angle be 'x'
The angles on the same side of the transversal are supplementary, that means they add up to 180 degrees.
⇒ [tex]40+x=180[/tex]
⇒ [tex]x=140[/tex]
The opposite interior angles are equal.
Hence we can conclude that the angles of parallelogram are 40°, 140°, 40°, 140°.

Bruce has 97 sports cards. 34 of them are football cards. Which equation can be used to find the number of sports cards y that are not football cards
Answer: 34 + y = 97
Step-by-step explanation:
According to the question,
Total number of sport cards = 97
In which some are foot ball cards and some are non football cards.
Let y be the number of sports cards.
Given, 34 cards are football cards.
Therefore, total number of cards = 34 + y
⇒ 34 + y = 97
Which is the equation that will use to find the number of non football cards.
To find the number of sports cards that are not football cards, you subtract the number of football cards from the total number of sports cards. The equation is y = 97 - 34.
To determine the number of sports cards that are not football cards, you need to subtract the number of football cards from the total number of sports cards.
Step-by-Step Explanation:
The total number of sports cards is 97.
The number of football cards is 34.
The number of sports cards that are not football cards can be found by subtracting the number of football cards from the total number of sports cards: y = 97 - 34.
Therefore, the equation y = 97 - 34 can be used to find the number of sports cards that are not football cards.

What are exponents and how do solve exponents questions?The exponent of a number shows how many times the number is multiplied by itself. The properties of exponents or laws of exponents are used to solve problems involving exponents. These properties are also considered major exponents rules to be followed while solving exponents.
Using quotient law [tex]\frac{a^{m} }{a^{n} } =a^{m-n}[/tex].
Now, [tex]\frac{5^{-6} }{5^{-4} }[/tex] can be written as [tex]\frac{5^{4} }{5^{6} }[/tex]
By using the quotient rule, we get [tex]\frac{5^{4} }{5^{6} }=5^{4-6}[/tex]
[tex]=5^{-2}=\frac{1}{5^{2}}[/tex]
=1/5×5=1/25
Therefore, the simplified form of the given expression is 1/25.

You bought 2 pairs of pants at $28.99 each, and one shirt at $21.34. If the tax rate is 5%, what is the total cost of your purchase?
Show how you got the answer
Question 3 options:
$79.32
$58.98
$69.32
$83.29
The total cost of purchase on 2 pants and 1 shirt is $76.986.
Given that, you bought 2 pairs of pants at $28.99 each, and one shirt at $21.34.
What is the sales tax?Calculating the sales tax applied to a purchase is a matter of simply multiplying the tax rate by the purchase price using the equation sales tax = purchase price × sales tax rate. Adding the sales tax to the original purchase price gives the total price paid with tax.
Now,
The cost of 2 pairs of pants
= 2 ×28.99
= $57.98
Total cost of two pants and a shirt
= 21.34+51.98
= $73.32
Tax =5% of 73.32
= 5/100 ×73.32
= 0.05 ×73.32
= $3.666
Total cost of purchase =73.32+3.666
= $76.986
Therefore, the total cost of purchase on 2 pants and 1 shirt is $76.986.

In spherical geometry, what is the term used for the shortest distance between two points?
In the figure, what is the value of x?
Answer:x=90 °
Step-by-step explanation:
In any circle the exterior angle formed is half of the major arc - minor arc .
Angle formed by tangents or secants = [tex]\frac{1}{2}(Major arc - minor arc )[/tex]
The sum of measure of arcs inany circle is 360°.
Minor arc is given as x°.So Major arc = 360-x.
Substituting the given values in the formula :
[tex]x=\frac{1}{2}(360-x-x)[/tex]
[tex]x=\frac{1}{2}(360-2x)[/tex]
x=180-x
Adding x both sides we have:
2x=180.
Dividing both sides by 2.x= 90.
