Question

If the circumference of a circular sheet is 154 m,find its radius. Also find the area of the sheet. (Take π = 22/7​

Answer 1

Answer:

1886.5m square

Step-by-step explanation:

Here, Circumference=154m

So, the formula of circumference is 2pier

Let, radius be r.

pie=22/7

Put all values in the formula,

2pier=154

2*22/7*r=154

44/7*r=154

r=154*7/44

r= 24.5m

Here, we get the radius=24.5m

So, the formula of area =piersquare

. pie=22/7

put all the values in the formula,

piersquare=22/7*24.5*24.5

= 1886.5m square
