Answer:
Step-by-step explanation:
y varies with the square of x:
y = kx²
y equals 24 when x equals 10
24 = k·10²
constant of proportionality k = 0.24
when x = 20, y = 0.24·20² = 96

Answer:
The formula of the volume of a cylinder is known as follow
<h2>V= πr²h</h2>
Where
π is 3,14 or 22/7.
d (diameter) is a straight line segment that crosses a center and connects two points on the circle.
r is the radius of the to part of the cylinder.
h is the height.
we can subsitute to our formula knowing that
d = 4cm (turn to r = <em>2cm</em>,because the formula use r) ; h = 11cm
V = πr²h
= 3,14 × 2² × 11
= 3,14 × 4 × 11
= 3,14 × 44
= 138,16 rounded off (138,2cm3) result
Since she has already ridden 7 miles out of 31 miles,
remaining miles to be ridden
= 31 - 7
= 24 miles
Let x be the number of miles she has to ride in each of the 4 days left.
4x = 24
x = 6
estimate value of :- 2.99548 is 3
estimate value of :- 1.8342 is 2
So 3•2=6
so 6 is your answer
