Question

2)

A solid cylinder has a radius of 5 cm and a height of 10 cm.
Work out the volume of the cylinder.
Give your answer correct to 3 significant figures.

Answer 1

785.0cm³

Explanation:

Formula of calculating volume of a cylinder
= π r²h (Pie × radius square × height)

Radius given = 5cm
Height given = 10cm

working: π × radius²× height
= π × 5² × 10
=785.5398
=785.0cm³ (3s.f)
