If a circle has circumference 100pi units, what is it’s area
const2013 [10]

Answer:

2500pi^2 units

Step-by-step explanation:

Circumference = pi * diameter

Circumference = pi * 100

Radius = diameter/2

Radius = 50

Area = pi * radius^2

Area = pi * 50^2

Area = pi * 2500

Area = 2500pi^2 units

jane and jill were simplifying the expression (2x2+x) +2(-x2+×) and obtained different answers . who is right and why?​
Romashka [77]

Answer: who ever arrives at the answer x=0/3 =0 is correct

Step-by-step explanation:

Even though I need supporting details from the individual answers of Jane and Jill to pass my own judgment.

Given the expression

(2x²+x) +2(-x²+×)=0

Let's us open the bracket

2x²+x-2x²+2x=0

Collecting like terms

2x²-2x²+x+2x=0

3x=0

x=0/3

x=0
