Diameter of beach ball is 42cm. find the surface area and the volume
Answers
Hey mate here is your answer
Answer:
SA=5538.96 cm², Volume=38772.72 cm³
Step-by-step explanation:
diameter =42
so ,radius will be half of it=21 cm
∴r=21 cm
now,
let us consider π=3.14
so now ,
volume of the beach ball=4/3 π r³
=4/3*3.14*21³
=now,
=4*3.14*3087
=38772.72 cm³
so now,
surface area of beach ball=4 π r²
=4 * 3.14 *441
=4 * 1384.74
=5538.96 cm²
The volume of the beach ball is 38772.72 cm³ and ,surface area of beach ball is 5538.96 cm²
Hope it helped you :)
Answer:
Diameter =42 cm
Radius =21 cm
Surface area of sphere = 4πr^2
= 4*22/7*21*21
= 4*22*21*3
= 5544cm ^2
Hope it help you ✌️❣️
