Answer:

$\huge\boxed{V = 359.01 mm^(3) }$

Use the formula V = 1/3(bh) to solve for the volume of the cone where b = πr² where π ≈ 3.14:

Find the area of the base:

b = π(7)²

b = 49π

b = 153.86 mm²

Find the volume:

V = 1/3(153.86 · 7)

V = 1/3(1077.02)

V = 359.006 ≈ 359.01 mm³.

A rocket is launched from the ground. The function h(t)= -4.9t^2 +180t models the height of a rocket launcher from the ground t seconds after it is launched. If all other factors remain the same, which of the following function models the height of a rocket above the ground after t seconds if it is launched from a platform 100 feet in the air?

(1) h(t) = -4.9t^2 +280t

(2) h(t) = -4.9t^2 +180t -100

(3) h(t) = -4.9t^2 +180t +100

(4) h(t) = -4.9t^2 +180 (t+100)
