Step-by-step explanation:
Answer:
Step-by-step explanation:
refers to the permutations of 5 items taken 3 at a time. To evaluate this, we use factorials as follows;
The factorial of an integer n is evaluated as;
Using this concept, the above expression can now be simplified as follows;
Therefore, the permutations of 5 items taken 3 at a time is 60.
The next expression, 
refers to the combinations of 6 items taken 4 at a time. The simplification utilizes similar concepts of permutations since we shall be involving factorials;
Therefore, the combinations of 6 items taken 4 at a time is 15.
The final step is to evaluate the product;
The equation used to find the surface area of a sphere is 4 x pi x r^2. The surface area of the sphere with a diameter of 16 inches would be
4 x 3.14 x 8^2 = 803.84. Therefore, the surface area of a sphere with a diameter of 16 inches would be 804 square inches. (rounded the decimal)
