The volume of a cylinder is 252π252π cm3 and its height is 7 cm.

1 answer:

8 0

V = (pi) * r^2 * h
h = 7
V = 252(pi)

252(pi) = r^2 * 7
252(pi) / 7 = r^2
36(pi) = r^2
sqrt 36(pi) = r
6 = r <==== radius is 6 cm

$50+x \leq 50$

Subtract 50 from both sides:

$50+x-50 \leq 50 - 50$

$x \leq 0$

hope this helps!

1. Points A and B are to be mapped onto a number line according to two equations. The solution to the equation 2/3 A= -24 is the

OleMash [197]

<span>The solution to the equation 2/3 A= -24 is the coordinate of point A.

2/3 A = -24
A = -24 / 2/3
A = -24 * 3/2
A = -72/2
A = -36

The solution to the equation 20=-b/0.5 is the coordinate of point B

20 = -b/0.5
20 * 0.5 = -b
10 = -b
10/-1 = -b/-1
-10 = b

A = -36 and B = -10

The distance between the two letters is 26 units. </span>

If someone could help!

Step-by-step explanation:

This time round, use SOH method (Sin angle = Opposite/Hypotenuse)

given Opposite = 7

Hypotenuse = 10

$\sin(x) = \frac{opposite}{hypotenuse} \\ \sin(x) = \frac{7}{10} \\ x = {sin}^{ - 1} ( \frac{7}{10} ) \\ = 44.4deg(nearest \: tenth)$
