Answer:

30 inches

Step-by-step explanation:

If a flying disc has 4 3/4 inch radius, its circumference to the nearest inch is 30 inches.

Formula: C=2πr

C=2πr=2·π·4 3/4≈30

To find the circumference, multiply the radius by 2, then multiply by PI.

4 3/4 x 2 = 9 1/2

9 1/2 x PI = 9 1/2 x 3.14 =  29.83

Rounded to the nearest inch = 30 inches.

A circle with area 81ㅠ has a sector with a central angle of 120°.
Mrac [35]

Answer:

<h2>84.78</h2>

Step-by-step explanation:

We have the area of a circle

A_O=81\pi

The sector with a central angle of

120^o

Calculate, what part of 360° is an angle 120°:

\dfrac{120^o}{360^o}=\dfrac{1}{3}

The same part of an area of a circle is an area of a segment.

Therefore:

A_S=\dfrac{1}{3}\cdot81\pi=27\pi

Use π ≈ 3.14

A_S\approx(27)(3.14)=84.78

Which best describes how to solve the equation for x.
prohojiy [21]

Answer:

B. multiply both sides by c.

Step-by-step explanation:

To solve the equation for x, you have to isolate the x variable on one side of the equation. To do this, do the opposite of any operation applied to x to remove other variables from the x's side of the equation:

x/c = d

multiply both sides of the equation by c to isolate x:

(x/c) * c = d * c

x = dc

Now x can be solved for.

Hope this helps :)
