Hello from MrBillDoesMath!
Answer:
1283.3
Discussion:
Volume of figure =
volume of cone + volume of cylinder =
(1/3) Pi r^2 h + Pi r^2 h =
(1/3) Pi (7)^2* 7 + Pi (7)^2 * 6 =
Pi * 7^2 ( (1/3) *7 + 6) = => using PI is approx 22/7
(22/7) * 7^2 ( 7/3 + 6) =
(22/7)* 49 (25/3) = 1283.3
Thank you,
MrB
Answer:
962
Step-by-step explanation:
Line y = –x + 4 intersects the line y = 3x + 3., this is the right answer
The new mean is 66.09
<u>Explanation:</u>
Mean weight of 20 students = 65kg
One student with 88kg entered the room.
New mean = ?
The above equation can further be written as:
New mean =
= 66.09
Therefore, the new mean is 66.09
