If Mars has a diameter of approximately 4200 miles, what is the volume of Mars.

Alex777 [14]

Answer:

Dimplified: $3.88$ × $10^{10}$ , or $38,800,000,000$

Unsimplified: $38,792,400,000$

Step-by-step explanation:

Remember, the volume of a sphere is $V=$ $\frac{4}{3}$ $\pi r^{3}$

This comes into: $3.87924$ × $10^{10}$

As we know, the shape of mars is a sphere.

Let me know if you have a question, or if it lets you not have the × $10^{10}$

Endpoint given the Midpoint: * The midpoint of RP is M(2, 4). If one of the end points is R(-1,7), find the coordinates of the o

marin [14]

Answer:

The coordinates of other point are: (5,1)

Step-by-step explanation:

Given coordinates are:

M(x,y) = (2,4)

R(x_1,x_2) = (-1,7)

We have to find the coordinates of other point (x2,y2)

The formula for mid-point is given by:

$M(x,y) = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$

Putting the values we get

$(2,4) = (\frac{-1+x_2}{2}, \frac{7+y_2}{2})$

Putting respective elements equal

$\frac{-1+x_2}{2} = 2\\-1+x_2 = 2*2\\-1+x_2 = 4\\x_2 = 4+1\\x_2 = 5\\And\\\frac{7+y_2}{2} = 4\\7+y_2 = 4*2\\7+y_2 = 8\\y_2 = 8-7\\y_2 = 1$

Hence,

The coordinates of other point are: (5,1)
