Question

Taking it = 3.14, find the diameters of the cireles whose area
(1) 2826 m2
(ii) 7.065 mm2 (iii)254.34 cm2 ​

Answer 1

Answer:

57.6 m

2) 3 mm

3) 18 cm

Step-by-step explanation:

1) r*r = 2826/3.14 = 831 , r= 28.82 so d=r*2= 57.6 m

2) r*r = 7.065/3.14 = 2.25, r=1.5 so d=r*2= 3 mm

3) r*r = 254.34/3.14 = 81, r=9 so d=r*2= 18 cm

Answer 2

2826m2 7.065mm3 iii 254.34. cm2
