Answer:

12.37 square inches

Step-by-step explanation:

The area of the dartboard can be figured from the diameter as ...

A = (π/4)d² = (π/4)(17.75 in)² ≈ 247.4495 in²

There are 20 sectors, all the same size, so the area of one of them is ...

sector area = (1/2)(247.4495 in²) ≈ 12.37 in²

3 feet 8 inches converted to inches is 3x12+8=44inches

44inches times 4 pieces is 176 inches.

176 inches converted back to feet and inches is 176/12=14 feet 8 inches so he would need 15 feet of board

Are you supposed to change decimals to fractions and fractions to decimals?

If yes,

0.5 = 1/2
