Answer:
Hello!! The answer is B. there are 2 formulas to calculate circumference. Hope that helps!
Answer:
-x+1
Step-by-step explanation:
We need to find an equation in the form
.
To find
, we use the formula:
We'll use the points
and
:
The value of
(the y-intercept) is the value of
when
, which is 25.
So the equation is
(choice A).
The square has equal sides measuring 52 inches, since the circle inside the square touched the side of the square, that makes the diameter of the circle to have an exact size with the side of the square which is 52 inches. To find out the area or square inches of cloth that was cut from the square, is to find out the area of the circle itself. Using the formula in getting the area of a circle, which is pi multiplied by the radius squared. Represent pi with 3.14 rounded up to the tenths place and multiply it with the radius that would be the half of the diameter of the circle which is 52, you'll get 26 and multiply 26 by 26, you'll have the answer of 2,122.64 square inches.
Two ways to find the base
sin(23) = x/30
x = 30*sin(23) = 11.7
or pythagorean theorem
base = 30^2 - 27.6^2 = 11.7
A = 1/2(11.7)(27.6) = 161.5 cm^2
