Answer 2

Step-by-step explanation:

First convert 2.1 m into cm(2.1 × 100cm = 210cm) and find the area (210 × 70 sq cm) now find the area of the circle (22/7 × 14/2 × 14/2) that gives 22/7 × 7 ×7 sq cm

Then divide the area of the plywood by area of the circle .. The answer is the number of discs that can be cut and the remaining wood = area of the wood - area of discs
