Here is the set up:
(1/4)/2 = (9/4)/y
Solve for y.
So, let's make these two values improper fractions so they're easier to work with.

Now,
Radius (r) = diameter ÷ 2
r = 14/2 in.
r = 7 in.
Now,
A = 4πr²
A = 4 × 22/7 × (7)² in.
A = 4 × 22 × 7 in.
A = 615.75 square in.
Thus, The area of the beach ball with a diameter of 14 in. is 615.75 square in.
