1. Volume of a Cone – Higher – GCSE Questions
These questions are the same format as previous GCSE exams.
COPY means they use the exact same numbers as the original GCSE question.
Otherwise, they are clone questions using different numbers.
The worksheets are provided in a variety of sizes.

Edexcel Higher: May 2017 Paper 1, Q15 1
A cone has a volume of 98 cm3.
The radius of the cone is 5.32 cm.
(a) Work out an estimate for the height of the cone.
Volume of cone = π r2 h h r
V = 97 ≈ 100
100 = x 3 x 52 x h
r = 5.32 ≈ 5
100 = 1 x 25 x h
r = 3.14 ≈ 3
= h = 4 4 cm

Jenny uses a calculator to work out the height of the cone to 2 decimal places.
(b) Will your estimate be more than Jenny’s answer or less than Jenny’s answer?
Give reasons for your answer.
More, because the numbers in the
numerator goes up and the numbers
in the denominator go down.
