The shaded areas add to 2/5 of the area of the circle, which is given by
A = πr²
Then the shaded area is ...
(2/5)A = (2/5)π(10 in)²
shaded area = 40π in²
A = πr²
Then the shaded area is ...
(2/5)A = (2/5)π(10 in)²
shaded area = 40π in²
Answer:
91%
Step-by-step explanation:
We can use the formula
- "is" is 90
- "of" is 99
- "percent" is what we are solving for so we will denote it as x
Substituting in our values we get
- We will need to cross multiply here to get (90)(100) = (x%)(99)
- This simplifies to 9000 = 99x%
- Dividing by 99 on both sides we get 90.9% → x = 91%
Check the picture below.
so we can say that two sides are "4" each in length, since opposite sides are equal, let's find how long the slanted sides are.
