Question

A wire is in the form a rectangle with dimensions  48m x 40m is rebent to form a circle. Find the area enclosed by the circle.
​

Answer 1

Answer:

the answer will be 4312m2

Answer 2

Answer:

L= 48m

B= 40m

Step-by-step explanation:

Perimeter of circle = Perimeter of rectangle

$\: \: \: \: \: \: \: \: \: \: \: \: \: 2\pi \: r \: = \: 2(l + b)$

2×22/7×r = 2(48+40)

2×22/7×r = 2(88)

2×22/7×r= 176

r = 176×7/2×22

r = 28m

Area of rectangle = L×B

= 48×40

= 1920m^2

Area of circle =

$\pi \: r {}^{2}$

= 22×28×28/7

= 88×28

= 2464m^2
