Answer:
500x1.5
Step-by-step explanation:
Step One
Figure out the actual change.
Change = 2.78 - 2.45
Change = 0.33
Step 2
Find the % change
% Change = 0.33/2.45 * 100 = 13.5%
4x1/2=2. 2 is less than 4 so it shows that it is false.
Use the formula to find the area of a circle: Area = pi times radius squared
Divide each diameter by 2 to get the radius
Ex) 50/2=25
A= pi times 25 squared
25^2=625
A= 625 times pi
A=2,587.5
