Question

If the circumference of a circular sheet is 176m, find its radius. Also find the area of the sheet. (Take π = 22/7 ) (b) Find the height ‘x’ if the area of the parallelogram is 24 sq cm and the base is 4 cm. * 5 points Captionless Image (a) Radius=28 m, Area = 2464 sq m (b) 6 cm (a) Radius=28 m, Area = 2464 sq m (b) 4 cm (a) Radius=14 m, Area = 2464 sq m (b) 6 cm (a) Radius=28 cm, Area = 2464 sq cm (b) 6 cm​

Answer 1

Answer:

Circumference of the circular sheet=154m

⇒2πr=154m

⇒r=

2π

154

⇒r=

2×22

154×7

=24.5m

Now, Area of circular sheet=πr

2

=

7

22

×24.5×24.5

=22×3.5×24.5=1886.5m

2

.

Thus, the radius and area of circular sheet are 24.5m and 1886.5m

2

respectively.
