Answer:

The area is 7850 square inches

Step-by-step explanation:

Given the circumference, we want to calculate the area

mathematically, the circumference is;

C = 2 pi r

So r is C/2 pi

Area = pi * r^2

Substitute value for r from circumference;

Area = Pi * c^2/4pi^2

Area = C^2/4pi

Area = 314^2/4 * 3.14

Area = 7850 Inches square

The price of a mobile phone decreased from $375 to $250 during a clearance sale. What is the percent of decrease in the price?
Tresset [83]
So decrease is 375-250=75

so convert 75/375 to percent
percent means part out of 100 so 
x/100=x%

divide 125/375=0.3333/1

multiply by 100/100=33/100=33%

the answer is 33% or B
