Circle the volume in cm^3 of a cylinder with the radius 5cm and height 8cm
Phantasy [73]

Answer:

<em>628 </em>cm^{3}

Step-by-step explanation:

Since the formula to find the volume of a cylinder is \pi r^{2}h, we just need to fill things in.

Since the radius is 5 and the height is 8 and we know that pi=3.14, our new equation is:

3.14*5^2*8.

5*5=25. Now we simplify.

3.14 * 25 * 8

78.5 * 8

<em>628 </em>cm^{3}

Hope this helps!! <3 :)
