First you need to find the area of the circle, which is πr^2
With a radius of 8 inches, the area of the circle will be π*8^2 or 64π.
Next you want to find the area of the 120 degree section of that circle.
120 degrees is 1/3 of a circle, so all you have to do next is multiply the are of the circle by 1/3 (because 360/120= 1/3).
(1/3)(64π) --> All you really have to do here is multiply 64 by 1/3 or divide it by 3 (because to divide by a number is the same a multiplying by it's reciprocal) so you get (64/3)(π).
64/3 is 21 and 1/3 or 21.333..., so however you choose to write it, I will leave the answer as (64/3)π squared inches.
So,
In order to simplify a fraction, we have to factor both the numerator and the denominator.
Cross out ones.
Answer:
216
Step-by-step explanation:
A=2(wl+hl+hw)=2·(12·2+6·2+6·12)=216
Write it in y= mx+b form. Subtract 5x from both sides to get 4y = -5x + 100. Divide by 4 so the answer would be y= -5/4x + 25.
Answer:
-1 1/3 as a mixed number (if they ask for it in simplest form, choose this one)
-4/3 as an improper fraction
Step-by-step explanation:
1. Keep, change, flip
4/5 x -5/3
2. Cross cancel the fives
4/1 x -1/3
3. Simplify
-4/3 or -1 1/3 (they're equivalent)
