The area of a circular ring can be found by subtraction the area of a small circle from that of the large circle. How to find the area of an annulus? Then we have to subtract the areas of both the circles to get the result. In the figure above it is the number of gray square units it takes to fill the annulus. How to find the exterior diameter of an annulus? Since an annulus is the region between two concentric circles, its area can be calculated by subtracting the area of inner circle from the area of the outer circle. The formula to find the annulus of the circle is given by: × ( 50 2 − 40 2 ) area = 3.14159. Let a be the area of the outer circle and 'a' be the area of the smaller circle. So, the area of the annulus is 339.12 m 2.

Find the area of the following annulus using π = 3.14. Surface area of the space enclosed by the inner circle. We know that the area of a circle is a= πr 2 Area of an annulus : Surface area of the space enclosed by the outer circle. Inner circumference of an annulus: Let a be the area of the outer circle and 'a' be the area of the smaller circle. Ρ = (r+r) ⁄ 2; ( see area of a circle):
