Can someone explain to me?

The answer is (it can be curved) because it's doesn't have to cross the origin and it's a U shape so it can't look like a straight line and it doesn't have a constant rate of change. :)

Please i need help on my math

Answer:

$V = \pi (2.5)^2h$

Step-by-step explanation:

The formula for the volume of a cylinder, is V = π r^2 h. It shows that the diameter is 5. But we need the radius. The radius is half of the diameter. So, 5/2. This gets you 2.5.

The equation is now:

V = π(2.5)^2h

This is the answer.

$V = \pi (2.5)^2h$

70% of a number is 98.

Anni [7]

Set up the proportion:
70% - 98
90% - x

$\frac{70\%}{90\%}=\frac{98}{x} \\
\frac{7}{9}=\frac{98}{x} \\
\frac{7}{9}x=98 \\
x=98 \times \frac{9}{7} \\
x=14 \times 9 \\
x=126$

The answer is D. 126.
