Math help please and thank u

Step-by-step explanation:

First of all we should know the radius of cone here radius (r) = 15 inch

π = 3.14

Now first calculating the area

Area (A)

= πr²

= 3.14 * 15²

= 706.5 inch²

Also

Here we can see the height of cone

height (h) = 21 inch

So now

Volume

= A * h

= 706.5 * 21

= 14836.5 inch ³

$35.59 in pounds

step-by-step explanation:

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
