Aleksandr [31]

Answer:

G 328 ft

Step-by-step explanation:

\cos(angleBAC)  =  \frac{AB}{AC}

\cos(55°)  =  \frac{AB}{400}

AB = 229.431 ft

AB² + BC² = AC²

229.431² + h² = 400²

h = 327.659 ft ≈ 328 ft

Tina has an old fish tank in the shape of a circular cylinder. The tank is 2 feet in diameter and 6 feet high. How many cubic fe
yanalaym [24]

Answer:

The tank can hold 18.84 cubic feet

Step-by-step explanation:

Given

Shape: Cylinder

D = 2ft -- Diameter

H = 6ft -- Height

Required

Determine the volume

First, calculate the radius (r)

r = \frac{1}{2}D

r = \frac{1}{2}*2ft

r = 1ft

The volume (V) of the tank is:

V = \pi r^2h

Substitute values for r and h

V = 3.14 *1^2*6

V = 3.14 *1*6

V = 18.84

<em>Hence, the tank can hold 18.84 cubic feet</em>
