In a circle of radius 10 cm, a sector has an area of 40 (pi) sq. cm. What is the degree measure of the arc of the sector?
Rashid [163]

Answer:

144°

Step-by-step explanation:

First, find the area of the circle, with the formula A = \pir²

Plug in 10 as the radius, and solve

A = \pir²

A = \pi(10²)

A = 100\pi

Using this, create a proportion that relates the area of the sector to the degree measure of the arc.

Let x represent the degree measure of the arc of the sector:

\frac{40\pi }{100\pi } = \frac{x}{360}

Cross multiply and solve for x:

100\pix = 14400\pi

x = 144

So, the degree measure of the sector arc is 144°

The circumference of a circle is 29.83 cm. What are the radius and diameter, respectively? Use 3.14 for pi.
nasty-shy [4]

Answer:

Diameter: 9.5

Radius: 4.75

Step-by-step explanation:

To find the diameter you divide the circumference by pi(3.14) and to find radius you divide the diameter by 2 since the radius is half of the diameter.

Adrienne operates the milkshake machine at Burgers and Shakes. on Monday she added whipped cream to 210 shakes.This was 70% of t
Natalka [10]

Answer:

Total number of milkshakes sold on Monday = 300

Number of milkshakes without whipped cream = 90

Step-by-step explanation:

Given:

Adrienne adds whipped cream to 210 milk shakes which is 70% of the total milk shakes sold.

To find the total milkshakes sold.

Solution:

Let the total number of milkshakes sold on Monday be = x

Percentage of milkshakes with whipped cream added to them = 70%

Number of milk shakes with added whipped cream can be given as:

⇒ 70\% \textrm{ of the total number of milkshakes}

⇒ 70\% x

⇒ \frac{70}{100}x  [Representing percent in fraction form]

⇒ 0.7x  [evaluating in decimals]

We know that the number of milkshakes with whipped cream added to them = 210.

So, we have:

0.7x=210

Solving for x

Dividing both sides by  0.7

\frac{0.7x}{0.7}=\frac{210}{0.7}

∴ x=300

Thus, total number of milkshakes sold on Monday = 300

Number of milkshakes without whipped cream = 300-210= 90

Read the word problem. Hershel buys 5 bags of cookies, 3 bags of granola, and several bags of fruit snacks from a bake sale. In
agasfer [191]

Answer : Hershel buys 2 bags of fruit snacks.

Explanation :

Since we have given that

Number of bags of granola =3

Number of bags of cookies = 5

Total number of bags he buys from the bake sale =10

\text{Remaining bags are of fruit snacks} =10-(5+3)=10-8=2

So, number of bags of fruit snacks = 2

Hence, Hershel buys 2 bags of fruit snacks .

It is a comparison type of word problem.  

As we just compare the items with the total items to get the remaining items.
