The volume of a cylinder is given by the formula;
Volume = πr²h, where r is the radius, and h is the height or the length
Therefore,
252 π cm³ = π r² (7)
r² = 252/7
= 36
r = √36
= 6 cm .
Hence, the radius of the cylinder is 6 cm

<h3>What is a function?</h3>
A function is an expression or rule that explains the relationship between a dependent and independent variable.
Given the function;
d= 45 t + 100
Where;
- d is the total distance
- t is the time taken
If t = 412 hours
Substitute into the formula
d = 45 ( 412) + 100
d = 18540 + 100
d = 18, 640 miles
Thus, the distance from their house the Bensons' after 412 hours will be 18, 640 miles

<em>these do not equal the same. </em>
step by step: 3x + 4 (2x + 5)
multiply 4 by 2x, which is 8, then multiply 4 by 5, which is 20.
simplify; 3x + 8x + 20
combine like terms; (3x + 8x) + (20)
you’ll come up with 11x + 20
step by step: 6x + 5x
just add the two together and... bam, you get 11x.
