the surface area of the sphere is π/4 cm^3
<h3>How to determine the surface area</h3>
It is important to know the formula for surface area and volume of a sphere
Surface area = 
Volume = 
First, let's determine the value of radius, r
The value for volume was given as 256/3π cm3.
Pi cancels out and we have cross multiply to get the radius
Make r the subject of the formula
![r = \sqrt[3]{\frac{768}{12} }](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%5B3%5D%7B%5Cfrac%7B768%7D%7B12%7D%20%7D)
![r = \sqrt[3]{64}](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%5B3%5D%7B64%7D)
r = 4
Let's substitute to find the surface area
Surface area = 
Surface area = π/4
Surface area = π/4 cm^3
Thus, the surface area of the sphere is π/4 cm^3

Q=2*s*L(T2-T1)/ (R2/R1)
1500000=2*30*10(275-22)/(R2/6)
1500000=600(253)/(R2/6)
1500000R2=600*253*6
1500000R2=910800
R2=910800/1500000
R2=0.6072.
Any polygon given by a list of 2D vertex coordinates has area given by the shoelace formula.
That's the absolute value of half the sum of the cross products of the sides. We form the table of the vertices. We include the first vertex at the end, then calculate the cross product of the side, (a,b) then (c,d) gives cross product ad-bc.

6 8 6(11)-8(2) = 66 - 16 = 50
2 11 2(3) - (11)(-4) = 50
-4 3
So the area is (1/2)(50+50) = 50
Answer: 50
Answer: 8+1.5+1.5=11 10+1.5+1.5=13 11+13+11+13=48
Step-by-step explanation:
Answer:
Mean: 12
Median: 11
Step-by-step explanation:
For the median you would put the numbers in order from least to greatest (5, 5, 6, 7, 10, 12, 17, 18, 20, 20) then find the middle. But in this case, since there is two in the middle, you add them and divide that number by 2.
For the mean, you add all of the numbers up together to get 120. Then divide by the amount of numbers there are, which is 10, to get 12.
