The base of a circular swimming pool has a radius of 26 m. 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 = 3.14)

Area = 1,592 square meters of tile.

Step-by-step 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

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
