Question

The Thompson Family are filling in their circular garden with new soil for the spring. The garden has a diameter of 24 cm. The cost of the soil is $5.50 per square centimeter. How much money are they going to spend to fill their garden with new soil?

Answer 1

$2488.46

Explanation:

This problem is on the mensuration of flat shapes.

firstly, we need to solve for the area of the garden.

given that the diameter d=24cm

the radius is d/2= 12cm

Therefore the area is expressed as

A= πr^2

A=3.142*12^2

A=3.142*144

A=452.448 cm^2

We are given that a square cm cost $5.50 to sandfill

therefore the entire garden will cost $5.50*452.448

$2488.46
