Answer:
502.4 cubic unit
Step-by-step explanation:
Given data
The parameter for the cylinder is as follows
Height h= 10units
Radius r= 4 units
We know that the expression for the volume of a cylinder is
V= πr^2h
substitute
V= 3.14*4^2*10
V= 3.14*16*10
V= 502.4 cubic unit
Hence the volume is 502.4 cubic unit
Answer:
C. greater than 90 and less than 180 degrees.
Step-by-step explanation:
An obtuse angle is angle in the second quadrant.
This angle is more than 
but less than 
.
Therefore the correct answer is option C.
Note however that a angle is called a right angle and an angle greater than 
but less than is called an acute angle.
