Question

35 POINTS PLS HELP WITH MATH

Answer 1

Step-by-step explanation:

3. if diameter = 14 cm

then r = 14/2 = 7 cm

hence Circumference = 2πr = 2×3.14×7 = 43.96 = 44 cm.

4.) Radius = 2.1 inches.

hence circumference = 2πr = 2×3.14×2.1 = 13.188 in or 13.2 in.

hope it helpd...

Answer 2

Answer:

a.43.86cm
