-5/4

Explanation: The number marked by the dot is 1.25. To convert decimals to fractions, think of it as a percent. 1.25% is like 125% (out of 100%) so that would be 125/100. Then divide by GCD (greatest common divider). GCD must be a multiple of both 125 and 100. The GCD in this case is 25. So divide numerator (125) and denominator (100) by 25 to get 5/4. Hope this helps :)

73.77ft^2

Step-by-step explanation:

8.1 is the radius of your circle

area of a circle is

A= pi times radius squared

8.1^2 = 65.61

65.61 times 3.14 = 206.0154

Ans - 11.5^2 = 73.7654

round = 73.77
