Lita must find the area of the sector enclosed by central angle QCR in circle C.

Points Q and R lie on circle C. The measure of angle Q C R is 74 degrees and the radius of circle C is 1 foot.


What steps should Lita take to correctly solve this problem?

A: Lita knows that m∠QCR=74∘ and that the whole circle has a measure of 360∘, so the portion of the area she wants to find is 74∘360∘.

To find the area of the sector, Lita must multiply 74°/360° times the area of the circle, which is πr² (Option A).

What is the Area of the Sector of a Circle?

Area of sector = ∅/360 × πr², where ∅ = central angle, and r = radius of the circle.

Given the following:

∅ = m∠QCR = 74°r = 1 ft.

The area of the circle she wants to find is: 74°/360°.

Since the area of the whole circle is, πr², therefore, to find the area of the sector, Lita must multiply 74°/360° times the area of the circle, which is πr² (Option A).

In a circle, a 225° sector has area 250pi in^2. What is the radius of the circle?

Answers

Answer:

r = 200

Step-by-step explanation:

[tex]Area of sector = (\frac{225}{360})[/tex]×πr² = [tex](\frac{5}{8})[/tex] ×πr²

[tex](\frac{5}{8})[/tex] ×πr² = 250π

[tex](\frac{5}{8})[/tex] ×r²   = 250

       r²   = [tex](\frac{8}{5})[/tex] × 250

       r²   = 400

       r    = 200 (r is a length so, it's positive)

find the value of angle a

Answers

Answer:

angle A = 153 degrees

Step-by-step explanation:

solve for the interior missing angle.

so from the interior we know that we have 2 angles

1 is 63 degrees and 1 is 90 degrees because we see that there is a right angle and all right angles = 90 degrees, we also know that the sum of all angles in a triangle should equal 180 degrees. if we have a 63 degree angle and a 90 degree angle we know that the sum of both of them is 153 degrees we still need to find that missing angle and we can do that by minusing 153 from 180 which is 27 so the measurement of the interior angle of the triangle is 27 but that is not what we are looking for but the answer is already given to us because we know that a straight line is 180 degrees so we just minus that missing angle from 180 degrees we conclude that A = 153 degrees

write an expression that is equivalent to 21h - 10h + 16 - 9 + 14h + 5 .

Answers

21h-10h+16-9+14h+5

Collect the like terms. Like terms are numbers that have the same variable (like x, y, a, n...)

Like terms are:
21h, -10h, +14h

And

16, -9, +5

So add/ subtract the like terms

21h - 10h + 14h= 25 h

16 - 9 + 5 = 12

You can’t add 25h by 12 so your final answer is

25h+12
Answer:
25h+2
Step by step answer
Combining like terms.
start with h
21h-10h+14h=25h
16-9+5=2
so:
25h+2

the inverse of the function f(x)=-x+3

Answers

Answer: [tex]f^{-1}(x)=-x+3[/tex]

Step-by-step explanation:

To find the inverse of a function replace f(x) with x and replace the original x with y

[tex]f(x)=-x+3\\x=-y+3[/tex]

Now solve for y

[tex]x=-y+3[/tex]

First subtract 3 from both sides

[tex]x-3=-y+3-3\\x-3=-y[/tex]

Now divide both sides by -1 (this will make y positive)

[tex]\frac{x-3}{-1} =\frac{-y}{-1} \\-x+3=y[/tex]

Now replace y with the inverse of f(x), [tex]f^{-1}(x)[/tex]

How do I solve this problem? Also, shouldn't the answer be square root 61 because you do 5^2+6^2=c^2?

Answers

Hey there!

Formula:

a = √p(diagonal)^2 + q(diagonal)^2 / 2

a = √p + q / 2


SOLVING FOR CURRENT EQUATION

a = √10^2 + 12^2 / 2

a = √10 * 10 + 12 * 12 / 2

a = √100 + 144 / 2

a = √244 / 2

a = √61

a ≈ 7.81


Thus, your answer is: √61


Or as you put….

5^2 + 6^2 = c^2

5 * 5 + 6 * 6 = c^2

25 + 36 = c^2

√61 or -√61 = c^2
