Question

2. Find the area of the circles, given that:
(i) radius = 14 mm
(iii) diameter = 9.8 m​

Answer 1

Answer:

I)area of the circle =πr^2

here r is the radius of the circle=14mm

area of the circle =22×14×14 /7 sq mm

=22×28 sq mm

=616 sq mm

ii)diameter=9.8 m

radius =9.8/2 m=4.9 m

area = 22×4.9×4.9/7 sq m

=22×4.9×0.7 sq m

=75.46 sq m

Answer 2

Answer:

i) 616mm

ii) 301.72 m

Step-by-step explanation:

i) area of a circle= πr^2

22/7 * 14*14

= 616mm^2

ii) area of a circle= πr^2

22/7 * 9.8 *9.8

= 301.84m^2
