Question

if the circumference of a circle is 64 inches what is the diameter use 3.14

Answer 1

Circumference of circle = 2.pi.r

 

 64 = 2.pi.r

 32=pi r

pi= 3.14

 

32 = 3.14 * r

 

10.19=r

 

radius = 10.19 ft

 

Area= pi.r2

       =3.14*(10.19)2

       =3.14*103.84=326.06 square feet

Answer 2

: it would be 60.86 because you subtract
