Given:
Funnel is in the shape of a cone.
Radius = 4 inches
Height = 10 inches
To find:
a) The volume of the funnel
b) How many quarts of oil are in the funnel.
Solution:
Volume of cone:


in³
The volume of the funnel is 167.47 in³.
1 qt ≈ 58 in³
To convert cubic inch to quarts divide by 58.

= 2.9 quarts
Therefore 2.9 quarts of oil are in the funnel.

The LCM of 10 12 and 14 is 420
420÷60=7
7 Hours after 8:15AM is 3:15PM
The LCM (Least Common Multiple) of two numbers is the smallest number that is a multiple of both.
Answer:
False equation: -2|8 - 6| - 6 = -10
Step-by-step explanation:
-2|8 - 6| - 6 = -12 True or false?
-2 | 2| - 6 = -12 Substract 8 - 6 = 2
-2 × 2 - 6 = -12 |2| = 2 absolute value of 2 is 2
- 4 - 6 = -12 -2 × 2 = -4 ( negative times positive = negative)
-10 = -12 False
