Answer:

Area= 78.5 cm² (3 s.f.)

Circumference= 31.4 cm (3 s.f.)

Step-by-step explanation:

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

In this question, the radius is 5cm thus r= 5.

Area of circle

= π(5²)

= 25π

= 78.5 cm² (3 s.f.)

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

Circumference of the circle

= 2(π)(5)

= 10π

= 31.4 cm (3 s.f.)
