The diameter of a circle is 7 feet. Which choice best represents the circles circumference? Use TT= 3.14A: 43.96 feetB: 21.98 feetC: 10.99 feetD: 49 feet

Respuesta :

the diameter of the circle is,

D = 7 ft

radius r = D/2 = 7/2

so the radius is r = 7/2

the circumference of the circle is

= 2 x pi x r

= 2 x 22/7 x 7/2

= 22

so the answer is appox 22 or 21.98

thus, the answer is 21.98 ft option b
