Answer:
Radius = 4 cm
Area = 16π cm²
Volume = 240π cm³
Step-by-step explanation:
Radius of the given cylinder = [tex]\frac{\text{diameter of the circular base}}{2}[/tex]
= [tex]\frac{d}{2}[/tex]
= [tex]\frac{8}{2}[/tex]
= 4 cm
Area of the circular base = [tex]\pi r^{2}[/tex]
Here 'r' = radius of the circular base
Area of the base = [tex]\pi (4)^{2}[/tex]
= 16π cm²
Volume of a cylinder is given by the formula,
V = πr²h
Here 'r' = radius of the circular base
h = height of the cylinder
By substituting the values in the formula,
V = π(4)²(15)
= 240π cm³
