Question

what is the surface area of this sphere?
round your answer to the nearest hundredth.
7.4 in
square inches

Explanation:

Step1: Identify the radius

The radius \( r = 7.4 \) in.

Step2: Apply surface area formula

Surface area of sphere: \( 4\pi r^2 \)
Substitute \( r = 7.4 \): \( 4 \times \pi \times (7.4)^2 \)

Step3: Calculate the value

\( 7.4^2 = 54.76 \)
\( 4 \times 54.76 = 219.04 \)
\( 219.04 \times \pi \approx 219.04 \times 3.1416 \approx 688.24 \)

Answer:

688.24
