The formula for the volume of a cylinder is
V=πr²*h where r=radius and h=height
plug in the data we know
V=π8²*2
V=π*64*2
V=128π
V=402.1cm³
Answer=402.1cm³
After sale, the price is $135
75% is $135
so 100%
(135/75) * 100
(135/3) * 4
45 * 4
$ 180
12 different combinations because 4 times 3 equals 12.
Suppose that Eldi has x years old now :
x + 4 = 3 × ( x - 10 )
x + 4 = 3x - 30
Add both sides 30
x + 4 + 30 = 3x - 30 + 30
x + 34 = 3x
Subtract both sides x
x - x + 34 = 3x - x
34 = 2x
2x = 34
Divide both sides by 2
2x ÷ 2 =34 ÷ 2
x = 17
_____________________________
Thus Eldi is 17 .
