You have to solve this integral

That integral is easy to solve:
525600[0.42 t^3/3 + 2.7t^2/2 - t] eavluated between the limits of the integral, i.e. 7 and 0.5
I mean, it depends what type of math you're doing but I can try!
Answer:
6.32
Step-by-step explanation:
The x difference:
-5 - -3 = -2
The y difference:
-2 - 4 = -6
Distance:
-6² + -2² = 40
√40 ≅ 6.32
Answer:
The radius is 6.1 cm
Step-by-step explanation:
The volume of a sphere is
V = 4/3 pi r^3
There is a typo in the problem.
We know the volume
950 = 4/3 (3.14) r^3
Multiply each side by 3/4
3/4 *950 = 3.14 r^3
712.5 = 3.14 r^3
Divide each side by 3.14
712.5/3.14 = r^3
226.910828 = r^3
Take the cube root of each side
226.910828 ^ (1/3) = r^3 ^ 1/3
6.099371323 = r
The radius is 6.1 cm
