My circle has a radius of 8ft. What is the distance of the circle?

What "distance" are you talking about? Diameter? Circumference?

What is the area of a circle with the radius of 32 cm????

In fig o is the center of circle AB- 3cm and BC -4 cm then find the area of the shaded region

To clarify, when you mention the "distance" of the circle, there are two possible interpretations:

1. Diameter: The diameter of a circle is the distance across it, passing through the center. To find the diameter of your circle with a radius of 8ft, you simply multiply the radius by 2. Therefore, the diameter of your circle is 16ft.

2. Circumference: The circumference of a circle is the distance around the edge or perimeter of the circle. To find the circumference, you can use the formula C = 2πr, where C represents the circumference, π (pi) is a mathematical constant approximately equal to 3.14159, and r is the radius. Plugging in the given radius of 8ft, the formula would be C = 2π(8ft) ≈ 50.27ft. So, the circumference of your circle is approximately 50.27ft.

Regarding your second question, to find the area of a circle with a radius of 32cm, you can use the formula A = πr^2, where A represents the area and r is the radius. Plugging in the given radius of 32cm, the formula would be A = π(32cm)^2 ≈ 3216.99cm². Therefore, the area of your circle is approximately 3216.99 square centimeters.
