The radius of the aluminum cylinder is 0.258cm
HOW TO CALCULATE VOLUME OF A CYLINDER:
- The volume of a cylinder can be calculated by using the formula below:
V=πr²h
Where;
V = volume (cm³)
r = radius (cm)
h = height (cm)
- To calculate the radius of the aluminum cylinder, the volume is required. The volume can be calculated using the formula as follows:
Volume = mass ÷ density
Volume = 1.22 ÷ 2.70
Volume = 0.452 cm³
- The radius can be calculated with the volume and height known as follows:
r = √v/πh
r = √0.452 ÷ (3.142 × 2.16)
r = √0.452 ÷ 6.78
r = √0.067
r = 0.258cm
Therefore, the radius of the aluminum cylinder is 0.258cm.
