Answers
Answer:
Area of inner circle is 13.86 cm^
Area of outermost circle is 38.2 cm^
Answer:
Sometimes the answer will be 24.63
Step-by-step explanation:
The area of the circle that have radius of 3.5 will be 22/7 * 35/10 * 35/10
= 22 * 0.5 * 3.5 (As we can cut 7 and 35)
=38.50 cm²
The area of the circle that have radius of 2.1 will be 22/7 * 21/10 * 21/10
=22*0.3*2.1 (As we can cut 7 and 21)
= 13.86 cm²
The area of shaded portion will be = Area of radius 3.5- Area of radius 2.1 cm
=38.50-13.86
=24.64 cm²
