Question

A circle has a radias of 12in. The diameter of the circle is _____in. In order to find the area of the circle, use the formula ____ The area of the circle is ____

Thanks

Answer 1

Answer: 144 pie square inches!

Explanation:

1st blank : is 24 square inches since the radius which is half the diameter is 12 square inches we can easily know that the diameter would be 24 square inches!

2nd blank : pie r squared is the formula! for all areas of the circles! the total length in other words the circumference of the circle would be 2 pie r basically multiplying 2 and pie and the radius.

3rd blank : the area of the circle is 144 pie (square inches)!

Answer 2

Explanation:

The diameter of the circle is twice the radius, so the diameter of the circle is 2 x 12 inches = 24 inches.

To find the area of the circle, we can use the formula A = πr^2, where A is the area of the circle and r is the radius.

So, for this circle, A = π(12 inches)^2 = 144π square inches.

Therefore, the diameter of the circle is 24 inches, the formula to find the area of the circle is A = πr^2, and the area of the circle is 144π square inches.
