The adjacent figure shows a model of the Earth. The sphere has a surface area of approximately 1,257 m2.
a) Calculate the radium and the circumference of the sphere.
b) Calculate the volume of the model.
b) The Earth has a diameter of about 12,740 km.
What was the approximate scale of the model?

Hello everyone, side c belongs to r what about a and b?
How do you get to 3.14
Hello, I need to find the steepest point, or the point with the highest gradient, of a 4th-degree polynomial function. According to my teacher, the gradient of the inflection point is always the steepest gradient of the entire function. However, the internet says that the gradient of the inflection point doesn't have to be the…
There are n people in a room who are currently greeting each other. Show that at any given time there are 2 people who have greeted the same number of people. Tip: Drawers: Possible number, how often you've greeted someone. Unfortunately, there are just as many drawers as pearls. Consider whether two drawers are mutually…
Head = 4pi*r2
The Radium r is searched
.
Parts by 4
Parts by pi
O/(4*pi) = r2
Draw the root
Wurz( 1257 m2/(4*pi) = r
.
Now you can determine V
Super, he doesn’t learn anything like that. Total stupid
It’s not that hard. What is the earth? If you know that, find out the right formula, set it up and change it.
I don’t know how to change the shapes, can you explain it to me?
What formula do you have to take?
Yeah, but you can’t do that in the middle of it. It’s not until you have the r on one side and the rest on the other.
you have to pull the root or not
Right. And then what is the opposite of it? Then you have to count on both sides.
Before the 4 stands a plus and before the pi once
You always have to take the reverse operation. What’s in front of the four? And what about the π?
I honestly don’t know how to make this r alone on one side you can explain it to me with a journey
Right. And now you have to see that what you’re looking for is on your own. I’d like to write your way here.
