Answer:
1. 32 and 64
2. 24 and 17
3. 43 and 48
4. 25 and 15
Step-by-step explanation:
The circumference of a circle is determined by the formula 2πr.
I'd say divide the circumference by two and youll be left with 60.5=πr .
then divide 60.5 by 3.14 to get r
which is approximately 19.26
now use the circle formula for area
A=πr²
A in terms of pi is
A = π*(19.26)²
