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.
Answer:none of the above

→ C
The ratio is equivalent because 1/20 is 5 which means 9/10 is equal
15u + 11u - 9d - 19d = -2d
It went up 26, down 28, a net change of down 2.
