Question

find the area of the following circle. radius=14mm, diameter=49m, radius=5cm​

Answer 1

Answer:

radius 14mm=88mm.Radius 5cm=31 whole  3/7

Step-by-step explana tion:

area of a circle is 22/7 multiply by radius multiply by 2  

Answer 2

Answer:

Answer is 616 mm², 1886.5 m²,550/7 cm²

Step-by-step explanation:

(a) Area of circle = π r ²

= 22 /7x14 x 14

= 22 x 2 x 14 = 616 mm²

(b) Diameter = 49 m

\ radius = 49/2 = 24.5 m \ Area of circle = π r²

= 22/7 x 24.5 x 24.5

= 22 x 3.5 x 24.5 = 1886.5 m²

(c) Area of circle = π r²

= 22/7 x 5 x 5 = 550/7 cm²
