angle of 51 degrees. Find to the nearest tenth in both cases:
(a) the length of AB in centimeters(b) the area of the sector in square centimeters

Please Help I Need This Done By The Next Hour The Sector Of A Circle Is Shown Below. It Has A Radius

Answers

Answer 1

Answer:

1. 9.8 cm

2. 44.5 cm^2

Step-by-step explanation:

1. To find the length of arc AB, we use the formula for the length of an arc

Mathematically, that will be;

theta/360 * 2 * pi * r

theta is the central angle which is 51

r is the radius which is 10 cm

So we have

51/360 * 2 * 22/7 * 10 = 8.9 cm

2. The area of the sector

we use the formula for the area of a sector here,

That is;

theta/360 * pi * r^2

51/360 * 22/7 * 10 * 10

= 44.5 cm^2

2nd person uses: you, your. (it sounds like the narrator is talking directly to you.)

3rd person uses: they, them he, her. (it sounds like someone is watching the story happening and is telling it from an outside point of view.

A soap factory packs 7 bars of soap into each family pack. How many family packs can be made with 4,900 bars of soap?

Answers

In each family pack, there are 7 bars of soap. To find the number of family packs that can be made with 4900 bars of soap, we need to divide 4900 into groups of 7.

4900÷7

=700

Therefore, 700 family packs can be made with 4900 bars of soap.

Answers

Answer:

I will try my best. Don't really know if this is correct.

Step-by-step explanation:

Well, first, you will have to get a mixed number, 9/2. And then divide 9/2 to 3/1. ( 9/2 divided by 3/1 = ? ) Then, multiply the equation. ( ? x 3 = 9/2 )

Last, draw a diagram to represent the answer.

9/2 = ? ? ? (Pretend that is a diagram) ? = 3/2 gallon

You will have to simplify the answer to get 3/2 gallon.

Look, I tried my best trying to explain everything, this question is very confusing and hard to do.
