So since 11/pi doesn't means 11 divided by pi but it means 11 pi
circumference=2pir
if circumerence=11pi
2pir=11pi
solve for r (radius)
divide both sides by pi
2r=11
divide by 2
r=5.5
area=pir^2
area=pi5.5^2
area=pi30.25
answer is area=30.25pi in^2
Answer:
In terms of π, the area of the shaded sector is 108πin²
Step-by-step explanation:
Area of the shaded sector, which is the major sector=x°/360(πr²)
A=270/360×π×(12in)²
A=¾π×144in²
A=108πin²( in terms of π)
The answer to your problem would be 38/ 45.
He can hit 3 out of every 12 bats. This can be translated to 3/12. We want to make the numerator 12, so we multiple the top by 4, so we have to do the same thing on the bottom. This fraction would be 12/48.
He has to bat 48.
Start by setting up your two sets of parenthses.

Inside, we have the terms that compose each binomial.
Since x² breaks down into x · x, we use an x in each binomial.
The second term is the factors of -12 that add to the coefficient
of the middle term but what is the coefficient of the middle term?
If there is nothing written there, it's understood to be 1.
So factors of -12 that add to -1 are 4 and -4.
So we have (x + 4)(x - 3) which is our answer.
