Which equation uses the distributive property to show 3 × 47 = 141? A) 3 + (40 × 7) = 141 B) 3 × (40 × 7) = 141 C) 3 + (40 + 7) = 141 D) 3 × (40 + 7) = 141

D) 3 × (40 + 7) = 141

Step-by-step explanation:

(3 × 40 = 120) + (3 × 7 = 21) = 141

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 !
