Please refrain from giving the direct anser

Ok so for this question to find the volume of any object is BxWxH right? It also can mean area x height. So to find the volume of this cylindrical you need to find the area of the circle

silvernight269:

The formula to find the area of a circle is pi x r^2

silvernight269:

The diameter is 5 as shown. To get the radius we need to divide the 5 by 2. We get a 2.5. So r=2.5. pi x 2.5^2 = A

silvernight269:

We will get 6.25 pi as the area of the cirlce

silvernight269:

All thats left is multiplying the area by height which is 7. 6.25x7=??

silvernight269:

And since in the multiple choice answers, the pi is left alone so once you find the answer to 6.25x7 just add the pi symbol
