Question

A cylinder has a volume of 175 cubic units and a height of 7 units. The diameter of the cylinder is

Answer 1

answer choices are
5units
10units
12.5units

Answer 2

\[V=\pi r ^{2}h\]
diameter=2r

Answer 3

i dont understand what is the radius ?

Answer 4

\[175=\pi r ^{2}h\]
\[\pi=\frac{ 22 }{ 7 },h=7,find r\]

Answer 5

ok so i got 21.98 when i multiplied 3.14 * 7 now what do i do

Answer 6

\[\frac{ 22 }{ 7 }r ^{2}*7=175\]
\[r ^{2}=\frac{ 175 }{22 },r=\sqrt{\frac{ 175 }{22 }}\]
calculate r
then diameter =2*r

Answer 7

r=2.82
diameter=2*2.82=5.6 nearly
