Question

What is the circumference of a circle with area 24cm. Give your answer to three significant figures.

Answer 1

Answer:

Circumference = 17.4 cm

Step-by-step explanation:

A = π$r^{2}$

24 = π$r^{2}$

$r^{2}$ = 24/π

r = $\sqrt{\frac{24}{\pi } }$ = 2.7639...

d = 5.5279...

C = πd

   = π5.5279...

   = 17.4 cm
