Question

find the circumference and area of the circle. express answers in terms of π and then round to the nearest tenth. find the circumference in terms of π c = 18π cm (type an exact answer in terms of π.) find the circumference rounded to the nearest tenth. c =

Explanation:

Step1: Sustituir el valor de π

Como \(C = 18\pi\) y \(\pi\approx3.14\), entonces \(C = 18\times3.14\).

Step2: Calcular el valor

\(18\times3.14 = 56.52\).

Step3: Redondear a la décima más cercana

\(56.52\approx56.5\).

Answer:

\(C = 56.5\) cm
