Area of circle is πr^2
<u>Here</u>,
• π = 3.14
• d = 10
• so, r = d/2 = 10/2 = 5
<u>substituting the values in the formula,</u>
Area = 3.14 x 5 x 5
Area = 3.14 x 25
Area = 78.5 m^2
Hence, option (c) is correct.
This is a simple percentage question. 6/100 * 1000 = 60 people have forgotten
let X equal initial string length
X / 16 = 7.3
X = 7.3 * 16
X = 116.8
