A phone sells for $245. It is now on sale for 20% off the original price April has a coupon for an extra 10% off the sale price.
To the nearest dollar, how much less than the original price will April pay for the phone?

the answer is 8

step-by-step explanation:

3.14 x 8x8

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
