Write the standard equation of the circle with center (-3, 5) and a diameter of 10. plez a dying math student in need

The general equation of circle with center (a,b) and radius r is given by

We know that radius = diameter /2 =10/2=5

Thus the equation of circle with center (-3,5) and radius 5 is given by

When expanding this, we get

x^2+6x+9+y^2-10y+25=25

x^2+y^2+6x-10y+9=0

This is the required equation of circle.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

i think the answer is a.( -3, -1 )
