Question

what is the surface area of this sphere? round your answer to the nearest hundredth 9 cm square centimeters

Explanation:

Step1: Identify the radius

The radius \( r = 9 \, \text{cm} \)

Step2: Apply surface area formula

Surface area of sphere: \( 4\pi r^2 \)
Substitute \( r = 9 \): \( 4\pi (9)^2 = 4\pi \times 81 = 324\pi \)

Step3: Calculate the numerical value

\( 324 \times 3.1415926535 \approx 1017.87601976 \)

Step4: Round to nearest hundredth

\( 1017.87601976 \approx 1017.88 \)

Answer:

1017.88
