Answer:
the circumstance would be 21.99
the area is 38.48
Step-by-step explanation:
radius is half the diameter so your radius is 3.5
The area of a circle is pi times the radius squared (A = π r²) which for you would be A = 3.14 × 3.5²
circumference is found by multiplying 2 times pi times the radius (C = 2πr) which for you would be C = 2 × 3.14 × 3.5
