If the center is in point P(a,b) and has a radius r then circle equation is:
(x-a)²+(y-b)²=r².
In your task we've got P(0,0) so the circle equation is x²+y²=r².
We have to find r. Radius start at (0,0) and end at (-4,-6) therefore
r=√((-4)²+(-6)²) and
r²=(-4)²+(-6)²=16+36=52.
So answer is x²+y²=52.
Answer: 14.7 (Rounded)
Work: So since (2 x 10) / 1/3 is in parentheses, I'm going to to that first. And since (2 x 10) is in parentheses in a parentheses, I'm going to do that multiplication first. After doing the multiplication, I get 20, and I'm going to divide it by 1/3 since it's in the parentheses. After dividing, I get 6.666..., But I'm going to round it to 6.7. Then, I'm going to add 6.7 by 8, and I got 14.7

#1. x= 5
(because it’s a 3,4,5 triangle and follows pythagorean theorem)
#2. x= 9
(225-144= 81, square root of 81 is 9)
#3. x= 8
(100-36= 64, square root of 64 is 8)
hope this helps!
Answer:
C. Hollow cone frustum
Step-by-step explanation:
Revolved it in my head, because the line isn't touching the triangle it will be hollow, because the triangle has a slope the shape will taper.
