I believe the answer is 221
Answer:
Therefore,
Surface area of Red sphere is 2826 square in.
Step-by-step explanation:
Given:
Blue Sphere Radius=20 in
Red Sphere Radius=15 in
pi = 3.14 ( also you can take )
To Find:
the surface area 'S' of the red sphere = ?
Solution:
Surface area of sphere for radius 'r' is given as
Substituting the values we get
For Red Sphere,
Radius = 15 in
Therefore,
Surface area of Red sphere is 2826 square in.
Similarly, you can find for Blue Sphere also
Also you will have different value for
