If you were trying to get the area of a whole circle, you would use
Area = pi r^2
You have to modify the formula to show that just part of the circle has an area that you are interested in.
The new formula is
Area = (theta/360) pi r^2
Givens
r = 30 cm
theta = 100
Solution
Area = (100 / 360) * pi * r^2 Substitute the givens into this formula
Area = (5 / 18) * pi * 3^2 Expand
Area = (5 / 18) * pi * 9 Cancel 9 into 18
Area = 5/2 * pi
Area = 2.5 * pi
Answer:so that’s a interior triangle so the mean your 2 points in the inside and the equation on the outside.
X=6
Step-by-step explanation:
(8x-4)+(3x+17)=(17x-23)
Combined our alike terms on the left side of the equation. So 8x+3x and -4+17.
11x+13=17x-23
Now this is what the equation should look like after combining ur alike terms.
11x+13=17x-23
-11x. -11x.
now u take the lowest x which is 11x and mince that from 17x but u only mince if it’s a positive but is it’s a negative u add it.
13=6x-23 so if u moved the x on the right side u move non variable number to the left but if u moved the x to the left u move the non variable number to the right so in this case the non variable number would be -23 so now u add 23 on both sides.
36=6x and now u just divide the 36 by 6 and remember to always divide by the x
Now the answer is x=6
Step-by-step explanation:
The Pythagorean theorem is:
where c is the hypotenuse.
The two wires in the sketch are the hypotenuse so we just use the formula
let the wires=x
So:
feet
