The equation for the circle below is x2 + y2 = 100. What is the length of the
circle's radius?

Answers

Answer 1
Answer:

Answer:

Step-by-step explanation:

x²+y² =(Radius)²

x²+y² =10². So the radius is 10
Answer 2
Answer:

Answer:

radius = 10

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ( where r is the radius )

x² + y² = 100 ← is in this form

with r² = 100 ( take the square root of both sides )

r = √(100) = 10
