Answer:
Step-by-step explanation:
let the side of outer square=2x
then x²+x²=(20√2)²
2x²=800
x²=400
x=√400=20 in
2x=2×20=40 in
area of outer square=40²=1600 in²
area of inner square=(20√2)²=800 in²
area of shaded region A=1600-800=800 in²
Answer:
Step-by-step explanation:
Diameter of the circle=
Circumference of a circle:
Area of the circle:
18.39 is 5.58% of 329.64.
We have to find that 18.39 is what percent of 120?
First, make the assumption that 329.64 is 100% as it is our output value.
We next represent the value we seek with x, therefore
100% = 329.64
And, x% = 18.39
Now, we get pair of simple equations
100% = 329.64 ........(1)
x% = 18.39 ........(2)
Now by simply dividing equation 1 by equation 2 and note of the fact that the LHS of both equations have the same unit (%);
100% / x% = 329.64 / 18.39
Taking the reciprocal of both sides, we get
x% / 100% = 18.39 / 329.64
or x = 5.58%
Hence, 18.39 is 5.58% of 329.64.
