Question

A sphere has the volume given. Find its surface area to the nearest whole number.
140 cm ^3

Answer 1

volume= v
\[v=\frac{ 4 }{3} \pi r^3 \]
\[r=\sqrt[3]{33.44}\]
r=3.221
surface area=A
\[A=4\pi r^2\]
A=130.308 cm^2

Answer 2

\[V=\frac{ 4 }{ 3 }\pi r^3=140 \]

Answer 3

yess continue to find r

Answer 4

Sphere Volume: \[V=(4/3)\pi r ^{3} \]Sphere Surface area:\[S=4\pi r ^{2}\]Use these and solve.

Answer 5

so how did you get the r @radar

Answer 6

That is what I think you need to solve for from the info provided by ikaram002p, but let me ponder a moment.

Answer 7

would it be \[r=\frac{ 3 }{ 4 }\pi (140)^{\frac{ 1 }{ 3 }}\]
