Answer:
Place the decimal before the last digit in both number i.e. 1602.3 and 65.4
Step-by-step explanation:
We are given the numerical expression 16023÷654.
Here, we have,
Dividend = 16023
Divisor = 654
it is required that the quotient of the division to be between 23 and 25.
If we take the numbers,
1602.3 and 65.4
This gives us,
.
Hence, placing the decimal before the last digit in both number will give the desired result.
Answer:
the volume is 

Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, a cylinder.
Given data
Volume v = ?
Radius r = r in
Height h= 2r in
We are expected to solve for the volume of a cylinder, given the above data we can substitute it in the formula for volume of a cylinder to obtain our result
we know that the expression for the volume of a cylinder is


Hence the volume in terms of the radius is
