volume of a sphere = 4/3 *pi * r^3
3/4 * pi = 4/3 *pi * r^3
divide each side by pi
3/4 = 4/3 * r^3
multiply each side by 3/4
3/4 * 3/4 = r^3
9/16 = r^3
take the cube root of each side
r = (9/16) ^ (1/3)
Answer:
Step-by-step explanation:
From the given data, it can be observed that there are two number that are abnormal and extremely different from others, 322 and 19. Eliminating these two numbers would reduce the error that can be generated.
Then to obtain the best single result from the measurements, find the mean of the other numbers.
i.e 52.3, 52.5, 52.2, 52.6
Mean = 
= 
= 52.4
Thus the best single result that can be obtained is 52.4.

Step-by-step explanation:
Area if cuboid =2(l*b+b*h+h*l)
= 2(7.5*5+5*2.3+2.3*7.5)
=2(37.5+11.5+17.25)
=2(66.25)
=103.75cm^3
Answer:
Step-by-step explanation:
Reasons:
3. The measures of supplementary angles add up to 180* (2)
5. Definition of Congruence (4)
6. Substitution Postulate (3,5)
