Question

The base of a circular swimming pool has a radius of 26 m.
`(3)/(4)` of the base has been laid with tiles. Find the area of the base of the swimming pool that has been laid with tiles. Give your answer correct to the 1 decimal place.

(Take
`\pi` = 3.14)

Answer 1

Area = 1,592 square meters of tile.

Explanation:

Basically find the area of the circle.

But we see that (3/4) of this circle base has tile.

so.

really find (3/4) (Area of Circle base)

A = (3/4) * π r^2

A = (3/4) * π (26)^2 sq. m.

A = (3/4) * π*676 sq. m

A = 3 * π * 169 = 507 π = 1,592.787 sq. m

but using pi = 3.14 only gets A = 1,591.98 sq. m
