Answer» Answer: Step-by-step explanation: 1) Diameter = 6 radius = 3 we know perimeter of a circle is 2 pie r but it a semi circle so its perimeter will be the HALF of the perimeter of 2 pie r so , 2 * 3.14 * 3 / 2 = 3.14 * 2 = 6.28 m 2) perimeter of the figure = perimeter of the semi circle + perimeter of rectangle so, 3.14 * 17/2 + 2 (17 + 5) 26.6 + 44 70.6 m (approx) 3) perimeter of the figure = perimeter of the semi circle + perimeter of rectangle + perimeter of the semi circle or perimeter of the circle + perimeter of rectangle 2 * 3.14 * 8 + 2( 16 + 8 ) 50.2 + 48 98.2 m (approx) 4) perimeter of the figure = perimeter of the semi circle (on the top , r = 4) + perimeter of rectangle + perimeter of the semi circle (on the BOTTOM r = 2) so, 3.14 * 4 + 2( 8 + 3) + 3.14 * 2 12.5 + 22 + 6.28 40.78 m (approx) THANK YOU |
