Question

From a rectangular sheet of acrylic of
dimensions 32 cm by 24 cm, 64 circular
buttons, each of diameter 3.5 cm,
have been cut out. Find the area of the
remaining sheet​

Answer 1

Answer:

152cm²

Step-by-step explanation:

area of sheet = l×b=32×24 =768

r = 3.5/2 = 1.75

area of circular buttons = πr² = 22/7 × 1.75×1.75 = 9.625

so area of 64 buttons= 9.625 × 64 = 616

area of remaining sheet = 768 - 616 = 152cm²

hope it helps!!!!
