Question

if the circumference of a circular sheet is 145 m find its radius find the area of the sheet use pie 22 by 7?? I want the answer of 145 not 154

​

Answer 1

Here the circumference of the circle is given to be 145 m

We will first find out the radius of the circle

Circumference of circle = 2πr

145 = 2πr

145 = 2 × (22/7) × r

r = 23.068

Now, we will find the area of the circle

Area = πr²

= (22/7) × (23.068)²

= 1672.416 m² (approx)

Hence, the radius and area of the circle will be 23.068 m and 1672.416 m²

Answer 2

Answer:

If 145 m is the circumference of a circular sheet, then it's radius and area are 23.068m and $1672.41 m^{2}$ respectively.

Step-by-step explanation:

Given

Circumference= 145 m

That is,

$2\pi r = 145\\\\2*\frac{22}{7} *r=145\\\\r= \frac{145*7}{2*22} \\\\=23.068m$

So the radius is 23.068m

Area of the sheet

$=\pi r^{2} \\\\=\frac{22}{7} *23.068*23.068\\\\=1672.41 m^{2}$
