Help me in this

Hello from MrBillDoesMath!

Answer: C)

Discussion:

To solve x^2 = 36/81 take the square root of both sides.

x = square root of (36/81)

As 36 = 6*6 and 81 = 9*9,

x = square root of (6*6)/ (9.9) or 6/9

But 6 and 9 share the common factor "3" so

x = 6/9 = (2*3)/(3*3) = 2/3

The last equality was gotten by cancelling the common factor 3.

A cylindrical jar's lid has a radius of 4 inches. If the volume is 351.68 in , approximately what is the height of the jar?

balu736 [363]

Answer:

7 inches

Step-by-step explanation:

The volume of a cylinder is calculated using

$V = \pi {r}^{2}h$

where r =4 inches is the radius and V=351.68 is the volume.

To find the height of the jar, we substitute these values and solve for h.

$351.68 = 3.14 \times {4}^{2} \times h$

$351.68 = 50.24h$

Divide both sides by 50.24 to get:

$h = \frac{351.68}{50.24}$

h=7 inches

Therefore the height of the jar is 7 inches
