QuestionWrite an expression for the surface area of a sphere: $A = 4\pi r^2$. Then, find the area for a radius of 25.4 cm.

Studdy Solution
Finally, calculate the surface area of the bubble.
$$Surface\, Area =4\pi \times645.16 =8119.44\pi$$The surface area of the bubble is $8119.44\pi$ square centimeters.
