plz answer fast

Answer 1

Answer:

Circle

Solve for diameter

d≈7cm

C Circumference

22

cm

Using the formulas

C=2πr

d=2r

Solving ford

d=C

π=22

π≈7.00282cm

Answer 2

Answer:

r = 3.5cm d = 7cm

Step-by-step explanation:

circumference = 2πr

22 = 2πr

r = 22 x 7/(2x22)

r = 7/2 = 3.5cm

d = 2r = 7cm
