Answer: r = 27/10

Explanation

(2r - 3)/4 = 3/5

Use cross multiplication:

5(2r - 3) = 3 x 4
10r - 15 = 12
10r = 12 + 15
10r = 27
r = 27/10

Find the volume of a cone with a height of 12 yd and a base diameter of 10 yd.
anyanavicka [17]

Answer:

The volume of the cone is 314yd³

Step-by-step explanation:

radius = half of diameter

d = 10yd

r = 10yd / 2 = 5yd

First of all to solve this problem we have to know the formula to calculate the volume of a cone

v = volume

r = radius  = 5yd

h = height  = 12yd

π = 3.14

v = 1/3 * π * r² * h

we replace with the known values

v = 1/3 * 3.14 * (5yd)² * 12yd

v = 1/3 * 3.14 * 25yd² * 12yd

v = 314yd³

The volume of the cone is 314yd³
