(a) $Area = 232.23\ cm^2$

(b) $Area = 52.78\ cm^2$

(c) Area = 373.06cm^2

Step-by-step explanation:

The area of a circle:

$Area = \pi r^2$

Where

$\pi = 3.14$

Solving (a):

r = 8.6cm

$Area = \pi r^2$

Area = 3.14 * (8.6cm)^2

Area = 3.14 * 73.96cm^2

Area = 232.2344cm^2

$Area = 232.23\ cm^2$ --- Approximated

Solving (b):

r = 4.1cm

$Area = \pi r^2$

Area = 3.14 * (4.1cm)^2

Area = 3.14 * 16.81cm^2

Area = 52.7834cm^2

$Area = 52.78\ cm^2$ --- Approximated

Solving (c):

r = 10.9cm

$Area = \pi r^2$

Area = 3.14 * (10.9cm)^2

Area = 3.14 * 118.81cm^2

Area = 373.0634cm^2

Area = 373.06cm^2 --- Approximated

The same way you would normally multiply but you just move the decimal as many times as it's moved on the top and bottom number
