Answer:
Angle
= (bigArc - smallArc)/2
Step-by-step explanation:
Draw a circle and put a point outside the circle. Draw two lines from the point. They are secants if they both touch the circle twice. See image.
The secants cut off a Big Arc and a Small Arc. The angle is the (BigArc - SmallArc) and then ÷ 2.
see image.
Answer:
8.22in
Step-by-step explanation:
Area of circle = πr²
r is the radius
Given
Area = 212in²
Substitute
212 = πr²
r² = 212/3.14
r² = 67.52
r = √67.52
r = 8.22in
hence the radius of the circle is 8.22in
