Answer» Area of circle = pirr 1) For radius r = 14 mm by Area = 22/71414 = 22214 = 616 mm^2 2) For radius r = 5 cm Area = 22/755 = 22*25/7 = 78.57 mm^2

Answer»

Area of circle = pi*r*r

1) For radius r = 14 mm by Area = 22/7*14*14 = 22*2*14 = 616 mm^2

2) For radius r = 5 cm Area = 22/7*5*5 = 22*25/7 = 78.57 mm^2
