Answer:
Hyperbola
Step-by-step explanation:
The cross section forms a hyperbola
Answer:
Option B is correct.
Step-by-step explanation:
It is given that :
The formula for the lateral surface area of a cylinder is
where
S represents the lateral surface area of cylinder,
r represents the radius of the bases and
h represents the height of the cylinder.
Solve for r;
Given:
Divide both sides by ,
Simplify:
Therefore, the radius of the bases of the cylinder is,
Answer:
B.66
Step-by-step explanation:
Perimeter =2(base+side)
2 x (13+20) = 66
The answer is 45
Solution:
Given expression is 4x + 5 + 2x + y.
To find the value of this expression when x = 6 and y = 4.
Substitute x = 6 and y = 4 in the given expression.
4x + 5 + 2x + y = 4(6) + 5 + 2(6) + 4
= 24 + 5 + 12 + 4
= 45
4x + 5 + 2x + y = 45
Hence, the value of 4x + 5 + 2x + y if x = 6 and y = 4 is 45.
