Answer:
75% of 200 = 50; 20% of 160 = 128
Step-by-step explanation:
200 (0.75) = 150
200 - 150 = 50
160 (0.20) = 32
160 - 32 = 128
Area of a circle = pi x r^2
Area of circle = 150,000/ 1578 = 95.06 square miles
95.06 = 3.14 x r ^2
Divide both sides by 3.14
R^2 = 30.27
Find the square root:
R = sqrt(30.27)
R = 5.5
The radius is c) 5.5 miles
All you need to do is multiply 3 yards by 10 yards to get 30 square yards.
Answer:
C
Step-by-step explanation:
First, let's work out the two triangles:
Area of triangle: bxh/2
2 x 8/2 = 8
Because there is two triangles multiply 8 by 2 = 16
To work out the area of the central rectangle:
Area of rectangle: l x w
3 x 8 = 24
Add 16+24 = 40 square feet
Correct me if im wrong but the answer is (B) hope this helps!
