Question

Find the difference between areas of two circles with radii 35 cm and 21 cm .​

Answer 1

Answer:

2464

Step-by-step explanation:

we know that ,

AREA OF CIRCLE = πr²

now,

area of c1 = 22/7× 35²

= 22/7× 1225

= 3850 cm ²

and,

area of c2 = 22/7×21²

= 22/7× 441

= 1386 cm²

differences area of c1 - c2

3850- 1386

= 2464 cm
