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)

Question

The surface area is
ft.2

Answer 1

The surface area (A) of a sphere is calculated using the formula:

\[ A = 4 \pi r^2 \]

where \( r \) is the radius of the sphere, and \( \pi \) is Pi, approximately equal to 3.14.

Given the radius \( r = 3.6 \) ft, we can plug the values into the formula:

\[ A = 4 \times 3.14 \times (3.6)^2 \]

\[ A = 4 \times 3.14 \times 12.96 \]

\[ A = 4 \times 3.14 \times 12.96 \]

\[ A = 4 \times 3.14 \times 12.96 \]

\[ A = 4 \times 3.14 \times 12.96 \]

\[ A = 4 \times 40.8384 \]

\[ A = 163.3536 \]

Now we round this to the nearest hundredth:

\[ A \approx 163.35 \] ft² (square feet)

So, the surface area is approximately 163.35 square feet.
