Question

what is the surface area of this sphere?
round your answer to the nearest hundredth.
14 m
____ square meters
submit

Explanation:

Step1: Find the sphere's radius

The diameter is 14 m, so radius $r = \frac{14}{2} = 7$ m

Step2: Use surface area formula

The formula for the surface area of a sphere is $SA = 4\pi r^2$. Substitute $r=7$:
$SA = 4\pi (7)^2 = 4\pi \times 49 = 196\pi$

Step3: Calculate and round

Compute the numerical value: $196\pi \approx 196 \times 3.14159265 \approx 615.75216$
Round to the nearest hundredth: $615.75$

Answer:

615.75 square meters
