Question

A monument in the form of a marble cylinder has a circular base with a radius of 1.5 meters. The altitude of the monument is 3.5 meters. How many cubic meters of marble does this monument contain? A. 7.07 m3 B. 24.74 m3 C. 21.21 m3 D. 6.19 m3

Answer 1

The formula of cylinder: 兀r^2×altitude
Take 兀 as 3.14

In this case,the equation will be:
兀1.5^2×3.5
=2.25兀×3.5
=7.875(3.14)
=24.7275
≈24.74

Thus the answer is B.24.74 m3.

hope it helps!

Answer 2

Option B. 24.74 m³

Explanation:

A monument in the form of a marble cylinder has a circular base with radius = 1.5 meters

Altitude of the monument = 3.5 meters

Marble required to prepare the monument = Volume of the monument

= π r² h

= (3.14)(1.5)²(3.5)

= 24.74 m³

Therefore, Option B. 24.74 m³ will be the answer.
