The diameter of a circle is 14 inches. Find the circumstance and area use 22/7
s344n2d4d5 [400]

Answer:

Circumference= 44 in

Area= 154 in²

Step-by-step explanation:

\boxed{circumference \: of \: circle = 2\pi  r}

Radius

= diameter ÷2

= 14 ÷2

= 7 in

Circumference of circle

= 2( \frac{22}{7} )(7)

= 44 in

\boxed{area \: of \: circle = \pi {r}^{2} }

Area of circle

=  \frac{22}{7} ( {7}^{2} )

= 154 in²
