The answer would be D just took test
Answer:
A = 1.5 π in² ≈ 4.7 in²
Step-by-step explanation:
the area (A) of the sector is calculated as
A = area of circle × fraction of circle
= πr² × 
= π × 3² × 
= 9π × 
= 1.5π in²
≈ 4.7 in² ( to the nearest tenth )
A = 1/3 * b * h....divide both sides by 1/3h
a / (1/3h) = b
3a / h = b <===
