Answer:
the volume of the whole shape is 676.35in^3
Step-by-step explanation:
the volume of the half cylinder is 196.35in^3
the formula used to find the volume is:
V = π * r² * h / 2
the volume of the cube is 480in^3
the formula used to find the volume is:
V = L*W*H

Step-by-step explanation:
Answer:
10√2
Step-by-step explanation:
If x=1+√2, evaluate x³+1/x³
--------
- x³+1/x³= (x+1/x)(x²-x*1/x+1/x²)=(x+1/x)(x²+1/x²+2-3)= (x+1/x)((x+1/x)²-3)
- x+1/x= 1+√2 + 1/(1+√2)= 1+√2+(1-√2)/(1-√2)(1+√2)= 1+√2 - (1-√2)= 2√2
- x³+1/x³= 2√2((2√2)²-3)= 2√2(8-3)= 10√2
Answer:
3
Step-by-step explanation:
If you divide both numbers by x then it's just 1 and 3. LCM of 1 and 3 is 3
