Question

find the diameter of the circle, whose area is:50.24meter square​

Answer 1

Step-by-step explanation:

Correct option is A)

Given area of circle is 50.24m

2

.

We know that area of a circle is=πr

2

, where r is the radius of the circle.

So, πr

2

=50.24m

r

r

{since,π=

}

r

2

=15.985

r=3.998m

We know that circumference of a circle is =2πr

So, Circumfrence =2π×(3.998)m

Circumfernce =2×

×(3.998)m

Circumfrence=25.12m

Answer 2

Answer:

Step-by-step explanation:

area = pie * radius ^2

50.24=3.14*radius^2

50.24/3.14=radius^2

radius ^2= 16

radius = 4 m

diameter = 8m
