Question 1 Report

Find, correct to 1 decimal place, the volume of cylinder of height 8cm and base radius 3cm. [Take π = 3.142]
Answer Details
The formula for the volume of a cylinder is V = πr2h, where r is the radius of the base of the cylinder and h is the height of the cylinder. Substituting the given values in the formula, we have: V = π(3cm)2(8cm) V = 72π cm3 V ≈ 226.1cm3 (rounded to 1 decimal place, using π ≈ 3.142) Therefore, the correct option is (D) 226.2cm3.
