Answer:
perimeter of circle=2πr
16=2πr
r=16/2π=8/πcm
now.
area of circle=πr²=π(8/π)²=π×64/π²=64/(22/7)=64×7/22=20.36cm²
Answer:
The scale of the map is inch = 20 feet.
This statement must be incorrect or the fraction of the inch is missing.
Because 6" long, at a scale of one inch = 20 feet, would only be 120 feet x 120 feet.
120 x 120 = 14,000 ft^2 and each of the four quadrants wouls only be 3600 ft^2.

Answer:
x = 10
Explanation:
Using Pythagoras Theorem:

8² + 6² = x²
x² = 64 + 36
x² = 100
x = √100
x = 10
