Answer:
42°
Step-by-step explanation:
This is right triangle and sum of 2 angles is 90°:
y+48°=90°
so y= 90°- 48°= 42°
Formula for surface area of a sphere of radius r is A = 4pi*r^2.
The same formula, for the case where the radius is 2.45 times greater, comes out to A = 4pi*[2.45r]^2.
Just find the ratio of
4pi*r^2 to 4pi*[2.45r]^2. It is 1/6.
