What is 1 1/4-5/6 PLEASE HELPPPPPP
2 answers:
here you go. I can explain if you want.
Firstly,you have to change the 1 1/4 to an improper fraction, by multiplying the denominator to the whole number then adding the answer to the numerator.
1×4+1 which equals to 5
so we now have 5/4
Secondly, we have to find a number that the denominators are both factors of. The answer to that is 12 because both four and six are factors of 12.

The volume of the composite figure is the third option 385.17 cubic centimeters.
Step-by-step explanation:
Step 1:
The composite figure consists of a cone and a half-sphere on top.
We will have to calculate the volumes of the cone and the half-sphere separately and then add them to obtain the total volume.
Step 2:
The volume of a cone is determined by multiplying with π, the square of the radius (r²) and height (h). Here we substitute π as 3.1415.
The radius is 4 cm and the height is 15 cm.
The volume of the cone :
cubic cm.
Step 3:
The area of a half-sphere is half of a full sphere.
The volume of a sphere is given by multiplying with π and the cube of the radius (r³).
Here the radius is 4 cm. We take π as 3.1415.
The volume of a full sphere cubic cm.
The volume of the half-sphere cubic cm.
Step 4:
The total volume = The volume of the cone + The volume of the half sphere,
The total volume cub cm. This is closest to the third option 385.17 cubic centimeters.
