Question

what is the surface area of this sphere?
round your answer to the nearest hundredth.
8.7 cm
square centimeters

Explanation:

Step1: Identify the radius

The radius \( r = 8.7 \, \text{cm} \)

Step2: Use surface area formula for sphere

Surface area \( S = 4\pi r^2 \)

Step3: Substitute radius into formula

\( S = 4 \times \pi \times (8.7)^2 \)

Step4: Calculate and round

\( 8.7^2 = 75.69 \), \( 4 \times 75.69 = 302.76 \), \( 302.76 \times \pi \approx 951.13 \)

Answer:

951.13
