How much fabric is needed to sew a spherical hot air balloon with a diameter of 15 m?
How much air is needed to inflate the balloon?

Correct answer:

S =  706.8583 m2
V =  1767.1459 m3

Step-by-step explanation:

D=15 m r=D/2=15/2=215=7.5 m  S=4π r2=4 3.1416 7.52=706.8583 m2
V=34 π r3=34 3.1416 7.53=1767.1459 m3
