Answer:
45% of 40 is 18% of <em>100</em>
Step-by-step explanation:
Let 45% of 40 = 18% of <em>x</em>
.
Taking LHS (Left Hand Side):
45% of 40
Taking RHS(Right Hand Side):
18% of x
Equating (1) and (2):
Hence, 45% of 40 is 18% of <em>100.</em>
Answer:
The answer to your question is diameter = 19.7 in
Step-by-step explanation:
Data
Circumference = 62 in
diameter = ?
Process
1.- Write the formula of Circumference, remember that circumference = perimeter.
Perimeter = 2πr
2.- Equal the equation to the value given
2πr = 62
-Solve it for r
r = 62/2(3.14)
-Result
r = 62/6.28
r = 9.87 in
3.- Find the diameter
diameter = 2r
diameter = 2(9.87)
diameter = 19.7 in
The answer to this question is 10000
Answer:
67.5 ft^2
Step-by-step explanation:
First find the area of the circle.
A = pi r^2
A = pi (8)^2
A = 64pi
There are 360 degrees in a circle
The shaded area has 121 degrees
The fraction is 121/360
The fraction shaded is 121/360
The fraction of the circle is the same as the area
121/360 A = 121/360 * 64 pi
area shaded = 67.54488889
To the nearest tenth
area shaded = 67.5
