Question

Taking pi=3.14 find the diameter of circle whose areA=2826m​

Answer 1

Area = pi ×r2

2826 = 3.14 × r2

2826/3.14 = r2

900 = r2

r = 30

Diameter = 2r

= 2× 30

=60 cm.

Answer 2

Answer:

Aera of circle is = πr²

2826 = 3.14×r²

2826÷3.14 = r²

900 = r²

√900 = r

r = 300

diameter = 2× r

diameter = 2 × 30

diameter = 60 m
