Answer:
12 ft²
Step-by-step explanation:
the rectangular hole area:
l • w = A
3 • 2 = 6 ft
the triangular hole area:
(b • h) / 2 = A
(4 • 3) / 2 = 6 ft
6 ft + 6 ft = 12 ft²
Answer:
V = π r^2 h
/3
Step-by-step explanation:
To find the volume of a cone, you need to plug in the measurement for the height of the cone and the radius of the base into the formula for the volume of a cone. Then simplify to get your answer.
Answer:
Explained below :)
(I tried my best, sorry if it doesn't make sense.)
Step-by-step explanation:
Example: 1/4 - 1/8= ?
1: Find the common denominator (bottom number)
2: If the common denominator is 8 then you multiply 1/4 by 2/2 to get the denominator of 8. If you needed then you can multiply the other fraction to get the same denominator.
3: Once you get multiply that then you get 2/8 -1/8.
4: Subtract the numerator (top number) 1
5: Keep the numerator (8)
6: Your answer would be 1/8
B. 10, 5, 2.5, 1.25, 0.625, 0.3125
You would just do 5.7-8.1, which is -3.6 degrees Celcius. Hope I helped!
