<span>Oh!
Think I did this one!! Lemme check my documents! Also can you give the unit and
lesson for this? When I get that, I’ll just edit this answer.</span>
Answer:
C.
Step-by-step explanation:
Sector = theta/360° × pi×radius×radius
40/360×22/7×10×10
4/36×22/7×100
1/9×22/7×100
22/63×100
2200/63=34.92 sq feets (approximately)
Option C is the answer . Don't get confused with decimals as maybe the person who provided these options used pi =3.14 instead of what i used i.e. =22/7.
2.5 x 13.7/ 4.9 + 1.6= 34.25/ 6.5 ≈ 5.27...
Exact answer: 34.25/6.5
