Question

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

Explanation:

Step1: Identify diameter and find radius

The diameter is 5.2 m, so radius $r = \frac{5.2}{2} = 2.6$ m.

Step2: Apply surface area formula for sphere

Surface area $SA = 4\pi r^2 = 4\times\pi\times(2.6)^2$

Step3: Calculate the value

$4\times\pi\times6.76 \approx 4\times3.1416\times6.76 \approx 84.9488$

Step4: Round to nearest hundredth

$84.9488 \approx 84.95$

Answer:

84.95 square meters
