An equation of the circle is
(x-h)² +(y-k)² =r²,
where (h,k) are coordinates of the center of the circle, and r is a radius of the circle.
We have h=2, k= -1, and radius r=diameter/2=10/2=5.
The equation of our circle is
(x-2)²+(y+1)²=25
Answer:
125
Step-by-step explanation:
5^3 = 5 ✕ 5 ✕ 5, and 5 ✕ 5 ✕ 5 = 125

Step-by-step explanation:
If you're asking how to simplify, then this is how you do it.
when a power meets another power but in brackets, then you have to multiply the powers. ¼ × 4 would be 1. i simplified 81 to 3⁴.
