Question- Diameter of circle whose area is 34cm^2 ?
Answer-. Formula (area of circle)
Area of circle - πr^2 (π=22/7)
Area of circle is given 34 cm square
Area of circle = πr²
34 = πr²
34 = 22 / 7 r²
r² = 34 × 7 / 22
r² = 10.81
r = √ 10.81
r = 3.28
Diameter = 2r = 3.28 × 2 = 6.56 cm
34 = πr²
34 = 22 / 7 r²
r² = 34 × 7 / 22
r² = 10.81
r = √ 10.81
r = 3.28
Diameter = 2r = 3.28 × 2 = 6.56 cm
