Answer:
vol = 6.23 cm3
Step-by-step explanation:
dia = 1.26 cm
length = 5.00 cm
vol = area * L
vol = (pi * 1.26² / 4 ) * 5
vol = 6.23 cm3
3,075ft^3 (cubic feet)
(the ^3 means to the power of 3. aka cubed)
Answer:
4.32
Step-by-step explanation:
You can multiply 16 by 0.27 to get the answer.
16*0.27=4.32
You can check your work with estimation because 27% is about 1/4 of the number, and just by looking at the number, 4 is 1/4 of the number.
If you choose one person from the group, you have a 12/20 chance of them being a girl. Now, if the first person is a girl, we have one less girl and one less person to choose from. So, the new probability for the second person is 11/19.
Then, we multiply the chances
12/20 * 11/19
3/5 * 11/19
33/95
