Question
What is the surface area of a sphere with a radius of 13 units?A.676 units2B.1014 units2C.845 units2D.507 units2
Solution
The surface area of a sphere can be calculated using the formula 4πr², where r is the radius of the sphere.
Step 1: Identify the radius of the sphere. In this case, the radius is given as 13 units.
Step 2: Substitute the radius into the formula.
Surface Area = 4π(13)²
Step 3: Calculate the square of the radius (13² = 169).
Surface Area = 4π(169)
Step 4: Multiply the result by 4π.
Surface Area = 4 * 3.14159 * 169
Step 5: Calculate the final result.
Surface Area ≈ 2123.71663382653 units²
So, the options provided do not include the correct answer.
