Answer:
222.51 (when rounded)
Step-by-step explanation:
Pi x r squared is the formula to find the area of a circle
153.94 + 12.57 + 56
= 222.51
You basically find the area of each circle by find their diameters. So half of the length shown on each circle.
5.5hours to drive264 miles
7 hours to drove (264÷5.5)× 7 =....
2(4x2)+2(1/2 4x3.5)+(4x2)
2(8)+2(1/2 14)+8
16+ 2(7)+8
16+14+8
38 sq. ft.
30 in = 2.5 ft
A = (1/2)(2.5 ft)(3 ft) = 3.75 ft²
Answer:
The standard deviation on the critical path = 0.834
Step-by-step explanation:
Variance of activity A (
) = 0.33
Variance of activity B (
) = 0.67
Variance of activity C (
) = 0.33
Variance of activity D (
) = 0.17
Thus the standard deviation on the critical path (
) =
+
+
+ ![V^2_{4}](https://tex.z-dn.net/?f=V%5E2_%7B4%7D)
=
+
+
+
= 0.6956
= 0.834
The standard deviation on the critical path = 0.834
