Question

Find the circumference of the circle. Give the exact circumference and then an approximation. Use - 3.14.29 cmThe exact circumference of the circle is(Simplify your answer. Type an exact answer in terms ofT.)The approximate circumference of the circle is(Type a whole number or decimal rounded to the nearest hundredth as needed.)

Answer 1

Given : the diameter of the circle = d = 29 cm

The circumference =

`2\pi\cdot r=\pi\cdot d`

The exact circumference of the circle =

`29\pi`

The approximate circumference of the circle :

`\begin{gathered} \pi\approx3.14 \\ circumference=3.14\cdot29=91.06 \end{gathered}`
