Question

A circular swimming pool of diameter 12.6m is to be covered by a plastic sheet. The sheet costs £1.25 per square metre. How much will the sheet cost?

Answer 1

Step-by-step explanation:

given a circular swimming pool

diameter of pool is 12.6m

radius of pool is 6.3m

area of pool sheet required =πr^2

= π x (6.3)^2

= π × 39.69

=3.14×39.69

=124.62m^2

cost of 1 m=£1.25

cost of 124.62m^2 =124.62×£1.25

cost is £155.77
