Answer: See explanation
Step-by-step explanation:
Circumference of a circle: 2πr
π = 22/7
r = d/2
r = 42/2
r = 21
2 × 21 × 22/7
42 × 22/7 = 924 ÷ 7 = 132
Circumference = 132m
Area of the circle: πr²
22/7 × (21²)
22/7 × 441 = 9702 ÷ 7 = 1386
Area = 1386 m²
Hope this helps!
Answer:
circumference = 131.9
area = 1385
yes they are the same
D-both a relation and a function
