Question

Please help me to solve this question.

Answer 1

Answer:

$314 \frac{2}{7} cm^{2}$

Step-by-step explanation:

Surface area of sphere= 4πr², where r is the radius of the sphere.

Given that the diameter is 10cm,

2(radius)= 10cm

radius= 10 ÷2

radius= 5cm

Surface area of sphere

$= 4( \frac{22}{7} )( {5}^{2} ) \\ = 314 \frac{2}{7} cm^{2}$
