Answer:
False.
Step-by-step explanation:
Two angles are complementary when added up, they give a result of 90°.
So, to this question to be true we have to do:
Angle 1 + Angle 2 = 90
But if we resolve 56° + 124° = 180, so this means that this question is false, as the addition of both angles doesn't have a result of 90°.
The lateral surface area of the cylinder = 80 sq cm.
Step-by-step explanation:
Given,
The circumference of the base of the cylinder is 16 cm
So, 2 X pi X r = 16 cm ( where r be the radius of the base)
Now, the lateral surface of the cylinder = 2 X pi X r X H ( where H be the height = 5 cm)
= 16 X 5 sq cm
= 80 sq cm
