Answer:
10 because it goes by 2 so 5 x2 is 10 so 3 x2 is 6 so its x 2
Answer:the answer is 420 :)
Step-by-step explanation:
Answer:
The area of a triangle is the base times height times 1/2. Please mark brainliest!!!!
The center is at origin O(0,0).
If it contains the point, P(-8,6), then the radius r is, by Pythagoras theorem,
r=sqrt((-8)^2+6^2)=10
The general equation of a circle at centre (xc,yc) with radius r is given by
(x-xc)^2+(y-yc)^2=r^2
Substituting r=10, (xc,yc)=(0,0)
the resulting equation is therefore
(x-0)^2+(y-0)^2=10^2
or simply
x^2+y^2=100
