​

Answer 1

Answer:

Answer:r = 6 • 3 cm

Answer:r = 6 • 3 cmStep-by-step explanation:

Answer:r = 6 • 3 cmStep-by-step explanation: using the formula

Answer:r = 6 • 3 cmStep-by-step explanation: using the formula c = 2 π r

Answer:r = 6 • 3 cmStep-by-step explanation: using the formula c = 2 π r solving for r

Answer:r = 6 • 3 cmStep-by-step explanation: using the formula c = 2 π r solving for r r= c / 2π

Answer:r = 6 • 3 cmStep-by-step explanation: using the formula c = 2 π r solving for r r= c / 2π = 39•6 / 2•π

Answer:r = 6 • 3 cmStep-by-step explanation: using the formula c = 2 π r solving for r r= c / 2π = 39•6 / 2•π = 6•30254 cm

Answer:r = 6 • 3 cmStep-by-step explanation: using the formula c = 2 π r solving for r r= c / 2π = 39•6 / 2•π = 6•30254 cm= 6•3 cm.

Answer 2

Answer:

Step-by-step explanation:

Circumference of a circle=2πr=39.6cm

⇒2×  7 /22

​

r=39.6

⇒r=  2×22 /39.6×7

​

=6.3‬cm
