The surface area of a sphere is 616m2. what is the volume of-the sphere (correct to two significant figures)? (take π = 3.142)
14 cm3
210 cm3
1,400 cm3
2,100 cm3
4,300 cm3
Correct answer is C
Surfacearea(A)=4πr2=616m2
solving, we have
r=7m
Volume=43πr3
Volume=4×3.142×733
Volume=4310.8243
= 1436.941m3≊
