Find the center, which is the midpoint of the two endpoints given.

(x1 +x2)/2 , (y1 +y2)/2

(4-2)/2 , (-3+5)/2

2/2 , 2/2

Midpoint = (1,1)

Find the radius, which is the distance from the center to an end point.

√(x2-x1)^2 +(y2-y1)^2

√(4-1)^2 + (-3-1)^2

√(3^2 + -4^2)

√9+16

√25

r = 5

The equation for a circle is written as (x-h)^2 + (y-k)^2 = r^2

h and k are the center points.

Replace the letters with their values to get:

(x-1)^2 + (y-1)^2 =25

WILL GIVE BRAINLIEST ANSWER! A circular flower bed is 21 m in diameter and has a circular sidewalk around it that is 33m wide. F
Alina [70]

Answer:

The area of the sidewalk is 144.44 m².

The 2-m wide walk adds 4 m to the diameter, making it 21+4=25.

Since the radius is half the diameter, r = 25/2 = 12.5.

The area of the entire bed with walkway is 3.14(12.5)² = 490.625 m².

The diameter of the bed is 21, so the radius is 21/2 = 10.5.

The area of just the flower bed is 3.14(10.5)² = 346.185.

The difference between the two is 490.625-346.185 = 144.44 m².  This is the area of the walkway.

1/2a + (-3a) - 3b - 0.7a
Anna71 [15]
If you would like to calculate 1/2 * a + (-3 * a) - 3 * b - 0.7 * a, you can do this using the following steps:

1/2 * a + (-3 * a) - 3 * b - 0.7 * a = 0.5 * a - 3 * a - 0.7 * a - 3 * b = - 3.2 * a - 3 * b

The correct result would be - 3.2 * a - 3 * b.
