Answer:

r = √(3V/(πh))
r ≈ 1.78 cm

Step-by-step explanation:

Multiply by the inverse of the coefficient of r², then take the square root.

$V=\dfrac{1}{3}\pi r^2h\\\\V=\dfrac{\pi h}{3}r^2\\\\r^2=\dfrac{3V}{\pi h}\\\\\boxed{r=\sqrt{\dfrac{3V}{\pi h}}}$

For V=50, h=15, this is ...

${r=\sqrt{\dfrac{3(50)}{\pi(15)}}=\sqrt{\dfrac{10}{\pi}}\approx\boxed{1.78\quad\text{cm}}$

A cartographer is painting a spherical globe whose surface is 326.7 sq. in. What is the maximum radius of the globe that the car

svlad2 [7]

Answer:

$S =4\pi r^2$

And since we know the surface area 326.7 in^2 we can solve for the value of r like this:

$r =\sqrt{\frac{S}{4 \pi}}$

And replacing we got:

$r =\sqrt{\frac{326.7 in^2}{4 (3.14)}}= 5.10 in$

And the best answer would be:

5.1 in

Step-by-step explanation:

For this case we need to use the formula for the surface area of a sphere given by:

$S =4\pi r^2$

And since we know the surface area 326.7 in^2 we can solve for the value of r like this:

$r =\sqrt{\frac{S}{4 \pi}}$

And replacing we got:

$r =\sqrt{\frac{326.7 in^2}{4 (3.14)}}= 5.10 in$

And the best answer would be:

5.1 in

18 is what percent of 60?

kolezko [41]

First you set up a proportion 18 over ? = 60 over 100 then cross multiply. 18*100=1800 then divide that by 60 and you get 30
or
18/60=x
0.30=x
30
hope this helps!!!!
