Question

find the surface area of the sphere leave a in terms of pi
1.r=60m
2.d=14cm

Answer 1

\[V=\frac{4}{3}\pi r^{3}\]

1)
\[V=\frac{4}{3}\pi 60^{3}=4800\pi\]

2)
\[V=\frac{4}{3}\pi 7^{3}=\frac{1372}{3}\pi\]

Answer 2

the answer coices for the first one are (3600^2,7200^2,14400^2,1800^2)
and the 2nd (784^2,196^2,28^2,98^2) @twvogels
