Question

a cylinder-shaped water tank is 160 cm tall and measures 87.92 cm around. what is the volume if the water tank? enter your answer as a decimal in the box. use 3.14 for pi.​

Answer 1

Answer:

The volume is equal to $98,470.4\ cm^{3}$

Step-by-step explanation:

step 1

Find the radius of the base of cylinder

we know that

The circumference of a circle is equal to

$C=2\pi r$

we have

$C=87.92\ cm$

assume

$\pi =3.14$

substitute and solve for r

$87.92=2(3.14)r$

$r=87.92/[2(3.14)]=14\ cm$

step 2

Find the volume of the water tank (cylinder)

The volume is equal to

$V=\pi r^{2} h$

we have

$r=14\ cm$

$h=160\ cm$

assume

$\pi =3.14$

substitute

$V=(3.14)(14)^{2} (160)$

$V=98,470.4\ cm^{3}$
