Find the equation of a circle whose center is at (-3, 7) and radius is 9 units.
timurjin [86]

Answer:

(x + 3)² + (y - 7)² = 81

Step-by-step explanation:

the equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k ) are the coordinates of the centre and r the radius

here (h, k ) = (- 3, 7 ) and r = 9 , then

(x - (- 3) )² + (y - 7)² = 9² , that is

(x + 3)² + (y - 7)² = 81

Answer:

Square root of 87.35 will be plotted between 9 and 10 as shown below.

Step-by-step explanation:

We are given that, 'The number line is numbered in tenths'

Also, the square root of 87.35 is given by,

\sqrt{87.35}=9.4

That is, we have to plot the point 9.4 on the number line numbered in tenths.
