The area of the surface given by
is 1. In terms of a surface integral, we have

By multiplying each component in
by 5, we have

and the same goes for the derivative with respect to
. Then the area of the surface given by
is

The answer is 48, because 6*8=48, 16*3 = 48, 24*2 = 48.
Answer:
44cm
Step-by-step explanation:
Formula for circumference, C = 2πr
where r is the radius
r = C / 2π
= 
=44 cm
r° = 158°
s° = 180° - r° = 180° - 158° = 22°
