Answer:
A = 121π in²
Step-by-step explanation:
The circumference (C) of a circle is
C = 2πr ( r is the radius )
Here C = 22π , that is
2πr = 22π ( divide both sides by 2π )
r =
= 11
The area (A) of a circle is
A = πr² = π × 11² = 121π in²
Answer: 10
Step-by-step explanation:
Hello there, 10 is your common difference. the numbers consecutively go up 10. You can also check by doing the third term minus the second or the 4th minus the 3rd.
