Answer:</h2>
The surface area of a shape is the sum of the area of all of its faces. To find the area of a cylinder, you need to find the area of its bases and add that to the area of its outer wall. The formula for finding the area of a cylinder is A = 2πr2 + 2πrh.
<h2>
Step-by-step explanation:</h2>
- Surface area of a cylinder = 2πr 2 + 2πrh
- Volume of a cylinder = πr 2 h
- You need to know the radius and height to figure both the volume and surface area of a cylinder.
- Answers for volume problems should always be in cubic units.
- Answers for surface area problems should always be in square units.
Answer:
x = 9
Step-by-step explanation:
-2x + 3 = -15
-2x = -18
x = 9
Answer:
Step-by-step explanation:
<u>We know that:</u>
- P = 7x + 20 − 2y
- x = 2
- y = 6
<u>Work:</u>
<u>Substituting the given values</u>
<u>Solving</u>
- => P = 14 + 20 - 12
- => P = 22
Hence, the value of P is 22.
