Since it is given that one hole = 0,79m^2
0,79=3,142 x radius^2
radius^2=3,142 Divided by 0,79
radius=Square Root of 3.97721512
radius=1.994295662
=1.99m^2 (3 Significant Figures)
Answer:
<em>17.1 feet</em>
Step-by-step explanation:
Scale drawing = 5.7 inches
scale = 1 inches = 3 feet
If 1 inches = 3 feet
5.7 inches = 
feet
solving for , we cross-multiply
x 1 = 5.7 x 3
= <em>17.1 feet</em>
5(11x-5)=85
55x-25=85
+25 +25
55x=110
---- -----
55 55
x = 2
