Step-by-step explanation:
Its a right angle triangle, with its opposite and adjacent values given so tan is used.
Answer:
x=11/5
Step-by-step explanation:
Firstly you should transfer the denominator to the RHS from LHS
So you'll get
2x+1=3(-x+4)
so now
2x+1=12-3x
2x+1+3x=12
5x+1=12
5x=12-1
5x=11
x=11/5
Answer:
3053.63cm
Step-by-step explanation:
quoted from adraimsp
"The formula for cylinder volume is
V1 = π * r^2 *h
while formula for sphere volume is
V2= 4/3 * π * r^3
Since the height of the cylinder is 12, we can substitute h the equation into
V1 = π * r^2 *12
The volume and radius of the cylinder are the same as the sphere, so we can combine both equations to find r.
V1= V2
π * r^2 *12 = 4/3 * π * r^3
12 = 4/3 * r
r= 12*3/4
r=9
After we find the radius, we can find the sphere volume
V2= 4/3 * π * r^3
V2= 4/3 * π * 9^3
V2= 3053.62 = 3054"
