George uses diagram to determine 30% of 60. what expression could george used?
a (0.10)(6)
b (0.10)(60)
c (3)(6)
d (3)(60)

d

step-by-step explanation:

in a an geometric explicit equation, the first number is the starting rate. in this case 10.

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 !
