Questionsurface area of a sphere =4πr2=4 \pi r^{2}, where rr is the radius. The sphere below has a radius of 6 cm . Work out the surface area of the sphere. Give your answer in terms of π\pi and remember to give the correct units.

Studdy Solution
Calculate the surface area:
A=4π(6 cm)2 A = 4 \pi (6 \text{ cm})^2 =4π×36 cm2 = 4 \pi \times 36 \text{ cm}^2 =144π cm2 = 144 \pi \text{ cm}^2
The surface area of the sphere is:
144π cm2 \boxed{144 \pi \text{ cm}^2}
