Question
Find the area $ A $ of a sphere if radius $r = 11500\, \text{cm}$.
Answer
$529000000\pi\, \text{cm}^2$
Explanation
To find area $ A $ use formula:
$$ A = 4 \cdot r^2 \cdot \pi $$After substituting $r = 11500\, \text{cm}$ we have:
$$ A = 4 \cdot \left( 11500\, \text{cm} \right)^{2} \cdot \pi $$ $$ A = 529000000\, \text{cm}^2 \cdot \pi $$ $$ A = 529000000\, \text{cm}^2 \cdot \pi $$This page was created using
