Question

1. a company needs to calculate the capacity of a cylindrical barrel with a diameter of 1.5 m and a height of 2 m. what is the radius of the barrel?

a. 2.25 m
b. 3 m
c. 0.75 m
d. 1 m

Explanation:

Step1: Recall the formula for radius

The formula for radius \(r\) in terms of diameter \(d\) is \(r=\frac{d}{2}\).

Step2: Substitute the given diameter

Given \(d = 1.5\) m. Substitute into the formula: \(r=\frac{1.5}{2}\).

Step3: Calculate the value

\(\frac{1.5}{2}=0.75\) m.

Answer:

C. \(0.75\) m
