8.235 X 10 -4exponent. The exponent is negative because you moved the decimal to the right instead of left :) hope this helps!
Answer:
The diameter is 14π
Step-by-step explanation:
We know the area of a circle is πr^2
let 49π=πr^2
Cancel the π's, and you get 49=r^2
Take the square root and you get r=7
The diameter of a circle is 2πr.
2π(7)=14π.
It’s c both are parallel to each other meaning they don’t intercept
