Answer:
D. 7.8 miles.
Step-by-step explanation:
So, to solve this, you need to use the Pythagorean theorem to find the distance from the baseball field to his home. You know two of the sides of the triangle formed, 6 and 5. The Pythagorean theorem is a² + b² = c². In this case, it would be 6² + 5² = c². If you solve this, you would find that c is 7.81024967591. Just round it to the nearest tenth like instructed. This would get you 7.8 as the answer.
Extra work just in case:
6² + 5² = c²
36 + 25 = c²
61 = c²
=
7.8 ≈ c

Answer:
5.9 ft
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
872 = 4/3 (3.14) r^3
872 =4.186666666 r^3
Divide each side by 4.1866666 on each side
872 / 4.186666666 = r^3
208.2802548 = r^3
Take the cube root of each side
(208.2802548)^(1/3) = r^3^(1/3)
5.927652012 = r
