Find the area of a circle with diameter 15cm

177 cm²

Step-by-step explanation:

Area of circle = r²

Radius = diameter/2 = 15/2 = 7.5

Therefore,

Area = 22/7 × 7.5 × 7.5

        = 176.7 = 177 cm²

The answer is

Step-by-step explanation:

Area of a circle is given by πr²

where

r is the radius

From the question we were given the diameter

To find the radius using the diameter we use the relation

diameter = 15 cm

radius = 7.5 cm

Substitute the value into the above formula and solve for the area

Area = (7.5)²π

= 56.25π

= 176.714586

We have the final answer as

176.71 cm² to 2 decimal places
