Answer: 2 times
Step-by-step explanation:
Hi, since 1000 milliliters = 1 liter
We have to convert the 2 liters into milliliters:
2 x 1000 = 2000 milliliters, so she is using a 2,000 milliliters pincher.
Now we have to multiply the number of friends (10) by the amount of lemonade she serves to each one (400 ml)
400 x 10 = 4,000 milliliters
Finally, we have to divide the amount of lemonade she needs to serve (4,000 ml) by the capacity of the pitcher (2,000), to obtain the number of times that she will need to fill the pitcher.
4,000/2,000=2 times

Answer:
The first choice.
Step-by-step explanation:
Your graph should look like one below.
Formula of the Volume of a hemisphere:
V =


r³
144

=


r³
Multiply by 3 to cancel fraction in the right side
144

× 3 = 2

r³
432

= 2

r³
Divide by 2

on either sides to isolate r³

=

r³
2

and

cancel out
216 = r³
Take cube root to find the radius
![\sqrt[3]{216}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B216%7D%20)
=
![\sqrt[3]{r^3}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7Br%5E3%7D%20)
6 = r
Radius is 6 unitsThe formula of the surface area of a hemisphere is:
