3. What is the radius of the figure if the Area of the Sector is 288*pi? *

Alla [95]

Answer:

The radius of the circle is 36

x = 36

Step-by-step explanation:

Area of sector formula is:

$A=\frac{\theta}{360}*\pi r^2$

Given $\theta=80$ , and area (A) is $288\pi$ , we substitute and solve for r:

$A=\frac{\theta}{360}*\pi r^2\\288\pi=\frac{80}{360}*\pi r^2\\288\pi=\frac{2}{9}*\pi r^2\\288\pi=\frac{2\pi r^2}{9}\\2\pi r^2= 2592 \pi \\r^2= 1296\\r=\sqrt{1296}\\r=36$

Thus,

The radius of the circle is 36

x = 36

Answer:

50 cents per lollipop

Step-by-step explanation:

The full bag of lollipops costs 5.99 for 12 lollipops. You must use proportions.

5.99. _ X

———. ——

12. 1

Cross multiply to get 5.99 = 12x. Isolate the variable (x) by dividing by 12. 5.99/12 = 0.499166666666667

Because it is a price, round to the nearest hundredth and it costs about 50 cents per lollipop
