Question

The radius of a circle is 16.4 m. Find the circumference TO THE NEAREST TENTH

Answer 1

A = 845.0 m^2

Explanation:

The appropriate area formula is A = pi*r^2.

Here the area is A = pi*16.4 m)^2, or (to the nearest tenth) A = 845.0 m^2

Answer 2

103.0

Explanation:

`\boxed{ \bold{formula = 2 \: \pi \: r}}`

= 2 × 3.14 × 16.4

= 102.992 m

= 103.0 m
