Question

A tank is in the shape of a cylinder 7 feet tall and 10 feet and radius find the exact surface area of the tank

Answer 1

`2036.75088022^(2)` or
`2036.8^(2)` rounded to the nearest tenth

Explanation:

1. Find the area of the base and the top, which are circles.

Area of circle :
`\pi 10^(2)` = 986.960440109

There are 2 circles, soooooo....= 986.960440109 x 2 = 1973.92088022

2. Find the rest of the area of the cylander.

So, we have to find the circumference of the circle.

Circumference :2
`\pi`10 = 62.83

3. Multiply circumference by height.

62.83 x 7 = 439.81

4. Add all of the products.

439.81 + 1973.92088022 =
`2036.75088022^(2)` or
`2036.8^(2)` rounded to the nearest tenth
