Question

Find the diametre of a circle whose area is 77/8​

Answer 1

Answer:

The diameter of a circle is 3.5 m or 7/2.

Step-by-step explanation:

Given,

Area of the circle=77/8

πr²=77/8

22/7 x r²=77/8

r²=77/8 x 7/22

r²=539/176

r²=3.0625

r=(3.0625)¹/²

r=1.75 m

  d=2r

    =2 x 1.75 m

    =3.5 m

∴In ratio=7/2
