Question

From a rectangular metal sheet of sides 30cm and 40cm ,a circular sheet as possible, is cut of Fund the area of the remaining sheet
​

Answer 1

Answer:

493.5 cm^2

Step-by-step explanation:

length = 40 cm

breadth = 30 cm

the diameter of the biggest circle possible will be 30 cm.

=> radius = 1/2*30 = 15 cm

area of the circle = pi*r^2

=> area of the circle = 3.14*225

=> area of the circle = 706.5 cm^2

area of the remaining sheet = area of the rectangle - area of the circle

area of the rectangle = 30*40

= 1200 cm^2

=> area of the remaining sheet = 1200 - 706.5

= 493.5 cm^2
