The base of a right prism is a right triangle. the lengths of the legs of the triangle are 3 meters and 5 meters. the volume of the prism is 30 cubic meters. find the height of the prism. a. 2 m b. 4 m c. 6 m d. 10 m

The height = 4 m answer (B)

Step-by-step explanation:

∵ The volume of any prism = base area × height

∵ The base is a right angle Δ with 3 and 5

∴ Area the base = 1/2 × 3 × 5 = 7.5 m²

∵ the volume of it = 30 m³

∴ 30 = 7.5 × height

∴ The height = 30 ÷ 7.5 = 4 m

B.4 m

Step-by-step explanation:

The volume of a right prism is given by

V = Bh

Where B is the area of the base and h is the height

B  = 1/2 bh  where b is 3 and h =5

B = 1/2 (3) (5)

  = 7.5

V= Bh

30 = 7.5 *h

Divide by 7.5 on each side

30/7.5= 7.5 /7.5 h

4 =h

The height is 4 m

step-by-step explanation:

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
