## Step 1:We are given the area of the circles and we need to find the diameter. The formula for the area of a circle is , where is the area and is the radius. We can rearrange this formula to solve for the radius: . The diameter is twice the radius, so .## Step 2:We are given the area of the circles and we need to find the circumference. The formula for the circumference of a circle is , where is the circumference and is the radius. We can rearrange this formula to solve for the radius: \(r = C/(2\pi)\).## Step 3:We are given the circumference of the circles and we need to find the area. The formula for the circumference of a circle is , where is the circumference and is the radius. We can rearrange this formula to solve for the radius: \(r = C/(2\pi)\). The area of a circle is .
