Question

the diameter of a circle is 15 what will be the area​

Answer 1

Answer:

@Here is your answer@

Step-by-step explanation:

Use the formula A=π⋅r2

Area=56.25⋅π m or 2254⋅π m or approximately 176.7 m

Explanation:

The formula for the area of a circle is A=π⋅r2, where A is the area and r is the radius

The radius if half the diameter, so

r=12⋅d

r=12⋅15m

r=7.5m

Therefore,

A=π⋅r2

A=π⋅(7.5)2

A=56.25⋅π m or A≈176.7 m (correct to 1 decimal place)

Answer 2

Answer:

176.625 sq. units

Step-by-step explanation:

The diameter of the circle = 15 units

So, The radius of the circle = 15/2 = 7.5 units

Area of the circle = π r² =  3.14 * 7.5 * 7.5 = 176.625 sq. units.
