what is the surface area of a 10 inch balloon
If the balloon's radius is 6 inches --
A=4πr^2
A = 4 * 3.14 * 5^2
Typo correction.
I assume the balloon's radius is 5 inches.
To find the surface area of a balloon, we can use the formula for the surface area of a sphere, which is 4πr^2, where "r" represents the radius of the sphere.
In this case, we have a 10-inch balloon, so the radius of the balloon would be half of its diameter, which is 5 inches.
To calculate the surface area, we substitute the radius into the formula and perform the necessary calculations:
Surface Area = 4π * (radius)^2
Surface Area = 4π * (5 inches)^2
Now, we can simplify and calculate the result:
Surface Area = 4 * 3.14159 * 25 square inches
Surface Area ≈ 314.159 square inches
Therefore, the surface area of a 10-inch balloon is approximately 314.159 square inches.
