Best Answer

it is 60.75

The radius of a 9 in diameter circle is 9/2 = 4.5

Area of a circle of radius "r" is pi times the square of the radius

Therefore in our case it is pi x 4.5 x 4.5 which is equal to

3.1417 x 4.5 x 4.5 = 63.61 square inches

How would the area of a circumerancebe affected when the diameter of a circle is doubled or triple?

First of all, there's no such thing as the "area of a circumference". The distancearound the circle is called the "circumference", and the area of the circle is calledthe "area of the circle".-- When the diameter of the circle is doubled, the circumference is doubledand the area is multiplied by 4.-- When the diameter of the circle is tripled, the circumference is tripledand the area is multiplied by 9.-- When the diameter of the circle is multiplied by N, the circumference ismultiplied by N and the area is multiplied by N2 .
