Answer:
Step-by-step explanation:
The supplement to ∠1 = 180°-135° = 45° = ∠3, so m is parallel to j and l.
∠2 ≠ 45° and ∠2 ≠ 135°, so k is not parallel to j, l, or m.
Answer:
hi
Step-by-step explanation:
The answer is D, 1000pi
Use SA=2πrh+2πr^2.
Plug in the numbers A=2π*10*40+2*π*10^2.
and you get <span>3141.59.
divide by Pi and you get 1000</span>
