The spheres are similar. Find the surface area S of the red sphere. Round your answer to the nearest whole number. Blue Sphere Radius=20in Red Sphere Radius=15in Surface Area ≈ 5027in squared

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

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
