Answer:
408 cm^3
Step-by-step explanation:
You have to find the volume of each object individually. You first find the volume of the sphere, so you input the radius, which is 3, into the equation which comes out to be 108 cm^3. You then have to find the volume of the cylinder, and since you have the diameter of the cylinder, and you need the radius, and the radius is half of the diameter, you would input 5 into the equation as the radius, since half of 10 is 5. That comes out to be 300 cm^3, so then you add the two volumes together, which is 408 cm^3
30 - 29 = 1 for the first one.
I'm assuming you want us to solve for the unknown variable z
Combine like terms on the right side
Use the distributive property on the left side
Add both sides by 20 to cancel out the "-20" on the left side
Divide both sides by 10
That is the value of the known variable, z, in this equation. Let me know if you need any clarifications, thanks!
