Answer 1

Step-by-step explanation:

Given :

• radius of the sphere = 10.5 cm

To find :

• the surface area
• volume

then,,,,

• surface area = 4 × ( 22/7 ) × 10.5 × 10.5

= 4 × 22 × 1.5 × 10.5

= 1,386 cm^2

• volume = ( 4/3 ) × ( 22/7 ) × 10.5 × 10.5 × 10.5

= 4 × 22 × 0.5 × 10.5 × 10.5

= 4,851 cm^3
