We know that
area of a circle=pi*r²
for r=2 km
area of a circle=pi*2²-----> 12.56 km²
if 360° (full circle) has an area of---------> 12.56 km²
45°---------------------------------> x
x=45*12.56/360-----> x=1.57 km²
the answer is
1.57 km²
A balloon is a sphere and the volume of a sphere is V=4/3 π.R³
V= 4/3.π.(6³) = 4/3.π.216 = 288π unit³ or ≈ 905 unit³
Answer: Yes! -5 is greater than -9, because with negatives the smaller numbers are the greatest because they are below 0. Have a good day and Good Luck!
Step-by-step explanation:
Answer:
D(-2, 5).
Step-by-step explanation:
We are given that M is the midpoint of CD and that C = (10, -5) and M = (4, 0).
And we want to determine the coordinates of D.
Recall that the midpoint is given by:

Let C(10, -5) be (<em>x</em>₁<em>, y</em>₁) and Point D be (<em>x</em>₂<em>, y</em>₂). The midpoint M is (4, 0). Hence:

This yields two equations:

Solve for each:

And:

In conclusion, Point<em> </em>D = (-2, 5).
