Find the radius and diameter of a frisbee with a circumference of 11 pi inches.

nikdorinn [45]

Circumerence=2pir or dpi were r=radius and d=diameter
11pi=2pir
divid eobt sides by pi
11=2r
dvide 2
5.5=r

11pi=dpi
divide both sides by pi
11=d

diameter=11in
radius=5.5 in

What is the value of x, 6x +2=180

tester [92]

Answer: $x=\frac{89}{3}$ or $26\frac{2}{3}$

$\mathrm{Subtract\:}2\mathrm{\:from\:both\:sides}\\6x+2-2=180-2\\6x=178$

$\mathrm{Divide\:both\:sides\:by\:}6\\\frac{6x}{6}=\frac{178}{6}\\$

$x=\frac{89}{3}$

Answer:

$(\sqrt{30}-2\sqrt{5})\ m$

Step-by-step explanation:

we know that

The length of the side, s, of a cube with a surface area, SA is equal to the formula

$s=\sqrt{\frac{SA}{6}}$

Step 1

Find the length of the side, s, of a cube with a surface area of $180\ m^{2}$

we have

$SA=180\ m^{2}$

substitute in the formula

$s=\sqrt{\frac{180}{6}}$

$s=\sqrt{30}\ m$

Step 2

Find the length of the side, s, of a cube with a surface area of $120\ m^{2}$

we have

$SA=120\ m^{2}$

substitute in the formula

$s=\sqrt{\frac{120}{6}}$

$s=\sqrt{20}=2\sqrt{5}\ m$

Step 3

Find the difference of the length sides

$(\sqrt{30}-2\sqrt{5})\ m$
