Circle Area question help please :)

Work out the area of a circle with circumference 9.8cm.
Give your answer correct to 1 decimal place!

Show working please :) thanks!

Circumference = 9.8 cm
2* pi * r = 9.8
6.283 * r = 9.8
r = 9.8 / 6.283
r = 1.559

Area = Pir^2
Area = Pi * (1.559)^2
Area = 7.6cm^2 to 1 dp.
