Hello!

We first have to find the volume of the bigger cylinder

We use the equation \pi  r^{2} h

Put in the values you know

\pi 10.5^{2} *18

This is 6234.49

Now we find the volume of the cut out part

\pi  7.5^{2} 18

This is 3180.86

We subtract the two values

6234.49 - 3180.86 = 3053.63

The answer is 3053.6

Hope this helps!

Whats the Approximate volume of the cylinder below in cubic centimeters?? Plz help
Sphinxa [80]

Answer:

Volume of a cylinder = 549.5 cm³

Step-by-step explanation:

Volume of a cylinder = πr²h

Where,

π = 3.14

Radius, r = 5 cm

Height, h = 7 cm

Volume of a cylinder = πr²h

= 3.14 * (5 cm)² * 7 cm

= 3.14 * 25 cm² * 7 cm

= 549.5 cm³

Volume of a cylinder = 549.5 cm³
