Plz explain your answer! i will mark at !

Cylinder: First you need to find the radius. To do that, you need to divide the diameter by 2

Then, you multiply it by itself

After that, you multiply it by the height

And finally multiply it by pi

Cone: First, you need to find the radius dividing the diameter by 2

Then, multiply it by itself

After that, divide the height by 3

Finally, multiply the radius times the height and then multiply it by pi

The answer to the cylinder is 251.2 and the answer to the cone is 251.2

The processes are the following:

Cylinder

D:8

R:4

V:π4^2*5

V:π16*5

V:80π

V:251.2

Cone

D:8

R:4

V:π4^2 15/3

V:π16*5

V:80π

V:251.2

so, converting firstly the mixed fractions to improper fractions and then "adding".

mean, 40.6
