Answer:
Radius r = 20.34 cm
The radius that can produces such a disk is 20.34 cm
Explanation:
Area of a circle;
A = πr^2
A = area
r = radius
Making r the subject of formula;
r = √(A/π) ........1
Given;
A = 1300 cm^2
Substituting into the equation 1;
r = √(1300/π)
r = 20.34214472564 cm
r = 20.34 cm
The radius that can produces such a disk is 20.34 cm
Answer:
I think it would be interviewing the researchers I'm unsure though
The fold was formed from something brittle. Since the syncline doesn't have properties from rock, it would be broken down easily.
because that is the right equation
Calculate them and you will know why the correct answer is D
