Question

A circle with radius of 6cm sits inside a circle with radius of 9cm.
What is the area of the shaded region while rounding to the nearest hundredth?

Answer 1

the area of shaded region is 125.6 square centimetres are we given two circles radius of incircle and radius of another circle is 19 area of shaded region = to area of larger circle - area of smaller circle

Answer 2

The area of the shaded region is 141.46 cm² ≈ 100 cm²

Step-by-step explanation:

radius of larger circle = 9 cm

area of the larger circle =

$\pi r^2 \\\\\frac{22}{7}\times (9)^2$

= 254.6 cm²

radius of the smaller circle = 6 cm

area of the smaller circle

$\pi r^2 \\\\\frac{22}{7}\times (6)^2$

= 113.14 cm²

area of the shaded region = area of the  larger circle - area of the smaller circle

= 254.6 cm² - 113.14 cm²

= 141.46 cm²

hence , The area of the shaded region is 141.46 cm² ≈ 100 cm²
