Question
Find the surface area of a sphere with a radius of 3.6 ft. Use 3.14 for pi. Round your answer to the nearest hundredth, if necessary.(1 point)
The surface area is
ft.2

The surface area can be calculated using the formula for the surface area of a sphere:

Surface Area = 4πr^2

Given a radius of 3.6 ft, we can substitute this value into the formula:

Surface Area = 4 * 3.14 * (3.6)^2

Surface Area = 4 * 3.14 * 12.96

Surface Area = 162.86 ft^2

Rounding to the nearest hundredth, the surface area of the sphere is 162.86 ft^2.

wrong

I apologize for the incorrect answer.

The correct calculation for the surface area of a sphere with a radius of 3.6 ft is:

Surface Area = 4 * π * (3.6)^2
= 4 * 3.14 * 12.96
= 162.86 ft^2

Therefore, the surface area of the sphere is 162.86 ft^2.

the answer is not 162.86 ft^2

I apologize for the mistake in my previous response.

Let's calculate the surface area correctly.

Surface Area of a sphere = 4πr^2

Given that the radius is 3.6 ft and using 3.14 for pi, we can substitute these values into the formula:

Surface Area = 4 * 3.14 * (3.6)^2

Surface Area = 4 * 3.14 * 12.96

Surface Area ≈ 163.07 ft^2

Therefore, the surface area of the sphere with a radius of 3.6 ft is approximately 163.07 ft^2.
