Y=mx+b
b= -2
m= rise/run = 2/3
y=2/3x-2
First find the radius by taking half the diameter. Use the radius to find the base area by using the formula for the area of a circle. Find the product of the base area and height, and then take one-third of the product.
Here’s how you would work it out
23 1/8
(7+15) + (1/4 +7/8)
22 + 2/8 + 7/8
22+ 9/8
23 1/8
