Question

A sphere has diameter 6 cm. The surface area of the sphere is

Answer 1

Answer:

113.15

Step-by-step explanation:

TSA of sphere=4πr^2

Hence TSA =113.15 cm²

Answer 2

Answer:

113.1 c

$surface \: area \: of \: sphere = 4 \: \pi \: {r}^{2} \\ = 4 \times \frac{22}{7} \times 3 \times 3 \\ = \frac{88 \times 9}{7} \\ = \frac{792}{7} \\ = 113.1 \: {cm}^{2}$
