Answer:
shaded part = 116cm² (3sf)
Step-by-step explanation:
area of larger circle:
a = πr²
= π x 6.5cm²
= 132.7322896cm²
area of smaller circle:
a = πr²
= π x 2.3cm²
= 16.61902514cm²
132.7322896 - 16.61902514 = 116.1132645
shaded part = 116cm² (3sf)
Hope this helps. :)
The shaded part of the circle is 116cm² (3sf)
How to find the shaded region?
To find a shaded region, First, take the area of the larger circle and the area of the smaller circle. Then subtract to find the shaded region.
Area of a larger circle:
a = πr²
= π x 6.5cm²
= 132.7322896cm²
Area of a smaller circle:
a = πr²
= π x 2.3cm²
= 16.61902514cm²
= 132.7322896 - 16.61902514 = 116.1132645
Shaded part = 116cm²
The area of a circle is pi times the radius squared (A = π r²).
