Write the standard equation of a circle with center (2, −5) and radius 16.
astra-53 [7]

The standard equation of circle when center is (h,k) and radius is 'r'

\left ( x - h \right )^{2} + \left ( y - k \right )^{2} = r^{2}

h = 2 and k = - 5, radius = 16

So equation of the circle is given by

\left ( x - 2 \right )^{2} + \left ( y - (-5) \right )^{2} = 16^{2}

\left ( x - 2 \right )^{2} + \left ( y + 5) \right )^{2} = 256

Whitepunk [10]
Steps:
1. To do this problem, you have to divide the area by the length
2. To make this easier, turn both numbers into improper fractions
143/32 divided by 11/4
3. To divide you actually have to multiply by the reciprocal
143/32 times 4/11 equals 572/352
4. Turn 572/352 into a mixed number which is 1 220/352
5. Now you simplify it by dividing the numerator and denominator by 44
6. Your answer is.
