How much water will a cone hold that has diameter of 6 inches and a height of 21 inches

197.92 square inches

step by step:
volume of a cone is V=πr^2h/3

1. divide diameter by 2 to find radius

r = diameter/2
r = 6”/2
r = 3”

2. plug in known values of r and h to find V

V = πr^2h/3
V = π(3”)^2(21”)/3
V = π(9”)(7”)
V = 197.72 square inches

The answer is 76° i believe
