A) 4748 inches
B) 3784 inches
C) 2894 inches
D) 3768 inches

Answer 1

D) 3768 inches

Explanation:

Given,

No. of plates = 100

Diameter of each plate = 12inches

So, radius of each plate = 12 / 2 = 6 inches

So, circumference of each plate

`= 2\pi \: r`

= 2 × 3.14 × 6 inches

= 37.68 inches

Hence, circumference of 100 plates = 100 × 37.68 inches

= 3768 inches

Hence, 3768 inches of gold trim is required (Ans)
