Question

From a circular sheet of radius 4cm, a circle of radius 3cm is removed.Find the area of remaining sheet
(take pi=3•14)​

Answer 1

Step-by-step explanation:

area of larger cirlce = PIE*r*r = 22/7 * 4*4 = 50.28cm^2.

are of smaller circle = PIE*r*r= 22/7*3*3 = 28.28cm^2.

Therefore area of remaining sheet = area of larger circle - area of smaller circle

= 50.28 - 28.28 cm^2

= 22 cm^2

ANSWER IS : 22 cm^2.

Thank you.

Answer 2

Answer:

(3.14×4^2)-(3.14×3^2) =simplify it you will get the answer
