Answer:

A = \dfrac{7}{2}\pi~cm^2

Step-by-step explanation:

There is a formula for the area of a sector given the radius and the angle measure.

A = \dfrac{n}{360^\circ}\pi r

n = angle measure

r = radius

A = \dfrac{140^\circ}{360^\circ}\pi \times (3~cm)^2

A = \dfrac{14}{36}\pi \times 9~cm^2

A = \dfrac{7}{18}\pi \times 9~cm^2

A = \dfrac{7}{2}\pi~cm^2

George bought 7.5 cases of pancake mix for his diner. A case contains 12 1.3-pound boxes. How many pounds of pancake mix did Geo
Ilya [14]
In order to get the answer to this problem, first we have to find out how many pounds does one case of pancake mix have. We know that one box has 1.3 pounds of pancake mix. We also know that one case has 12 boxes. So first, we multiply 1.3 to 12.  The answer we will get is 15.6. One case of pancake mix has a total of 15.6 pounds of pancake mix. Now we also know there are 7.5 cases that George bought. So in order to get the total pounds George bought, we multiply 15.6 to 7.5. So all in all, George bought 117 pounds of Pancake Mix.
