Question

What is the lateral area of a cone with a radius of 3.5 milliliters and a slant height of 8 millimeters?

Answer 1

The lateral of a cone with a radius of 3.5 milliliters and millimeters would be 28 `pi` or 87.92.

Explanation:

Right, let start by writing the formula of a cone.

L = `pi` rl

`pi` = pi
r = radius
l = slant height
L = Lateral Area (also known as the answer)

Now, we have a radius of 3.5 and a slant height of 8. Now, let plug the numbers into the formula.

L = `pi` (3.5)(8)
L = `pi` 28

Now, the answer is 28 `pi` millimeters but if you wanted the answer without being in terms of pi, you would multiply 28 times 3.14 (you would use 3.14 as the first 3 digits of pi) which would get 87.92 millimeters
