C, and D. They’re parallel so they’re never going to cross.
Answer:
5 significant figures
Step-by-step explanation:
Any first number than starts with > 0, it is counted as significant figures and with 0 in the middle of number, also will be counted. But if the first number is 0, you have to skip to the next number.
e.g
0.0567 = 3s.f
1.542 = 4s.f
0.0000012 = 2s.f
1200586 = 7s.f
87000000002 = 11s.f
Answer:
21870 km^2
Step-by-step explanation:
Area of sector=1/2r^2(theta)
Where r=18 km and theta=135
Area of sector=1/2(18)^2(135)
=1/2(324)(135)
=1/2(43740)
=21870 km^2
