The arc is one quarter of a circle so is 2pir, the other components of the quarter circle are the two radii, so perimeter is 2r+2pir = 2r(1+pi)

I believe 270 because a circle's perimeter is 360 so if you divide it by 0.75, you get 270.

The perimeter of a quarter circle is 2 radii plus a quarter of the circumference of the whole circle: → 2 × radius + ¼ × 2 × π × radius = 32.13 cm → radius × (2 + π/2) = 32.13 cm → radius = 32.13 ÷ (2 + π/2) cm ≈ 9.00 cm

Normally, the amount of the side of the rectangle below the quarter circle on it would expected to be calculated. However, the radius of the circle equals the amount that is subtracted, but in calculating the perimeter it has to be added back in again as it forms part of the perimeter. Thus the perimeter is the perimeter of the rectangle plus a quarter of the circumference of the circle. → perimeter = 2 × (20cm + 2 cm) + ¼ × 2 × π × 11 cm ≈ 44 cm + 3.14 × 11/2 = 61.27 cm.

Suppose the radius of the circle is r units. Then perimeter of a whole circle = 2*pi*r. So perimeter of curved part (arc) of a quarter circle = 2*pi*r / 4 = pi*r/2 Also, the quadrant has a radius on either end of the curved part. Their combined length is 2*r So the total perimeter = 2r + pi*r/2 = r(2 + pi/4)
