1.400 pi m^2
2.300 pi m^2
3.200 pi m^2
4.500 pi m^2

Answer 1

The surface area of a sphere is given by the formula A = 4πr^2, where A is the surface area and r is the radius.

Plugging in the given radius of 10 meters, we have:

A = 4π(10^2)
A = 4π(100)
A = 400π

Therefore, the surface area of the sphere is 400π square meters.
So, the correct answer is 400 pi m^2, which is not one of the given options.

Answer 3

To find the surface area of a sphere with a radius of 10 meters, we can use the formula for the surface area of a sphere, A = 4πr^2.

First, substitute the given radius into the formula:
A = 4π(10^2)

Next, simplify the expression inside the parentheses:
A = 4π(100)

Multiply 4π by 100:
A = 400π

The surface area of the sphere is 400π square meters.

Answer 4

no A=pir^2

Answer 5

Apologies for the mistake. You are correct, the formula for the surface area of a sphere is A = 4πr^2.

Given that the radius is 10 meters, we can substitute this value into the formula:
A = 4π(10)^2

Simplifying the expression inside the parentheses:
A = 4π(100)

Multiply 4π by 100:
A = 400π

Hence, the surface area of the sphere is 400π square meters.
