Question

Find the circumference and the area of a circle with diameter 7 cm. Use the value 3.14 for n, and do not round your answers. Be sure to include the correct units in your answers.​

Answer 1

the circumstance would be 21.99

the area is 38.48

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
