Find the circumference and area of each circle rounded to the nearest hundredth?

Answer 1

For circumference, multiply the diameter by pi and round the product to the second decimal place.

For area, multiply the square of the radius by pi and round the product to the second decimal place.

Answer 2

Without the distance of the radius or diameter, it is impossible to calculate.

However, the general algebraic eq'ns are

C = 2 pi r

or

C = pi d

&

A = pi r^(2)

Answer 3

Find circumference 17.3cm
