2. the larger circle of an annulus has a diameter of 10 cm, and the smaller circle has a diameter of 7.6 cm. what is the area of the annulus?

Area = 3.77 cm^2

Step-by-step explanation:

The diagram using the given statement is attached below

Diameter of larger circle is 10 so radius R1 = 10/2= 5

diameter of smaller circle is 7.6, radius (r1)= 3.8

We need to find the area of the shaded region

Area of the circle =

Area of annulus =

=

Area = 3.77 cm^2

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13

$450 i think. hope this ☺
