(15 POINTS) (SHOW WORK) FIND THE RADIUS OF THE CIRCLE

Given the equation, the radius of the circle is 7.

Step-by-step explanation:

We are given the equation, x² + y² = 49.

In order to find the radius, we have to calculate the square root of 49. This is because the original form of the equation is x² + y² = r².

So, the radius of the circle is 7.

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
