First you have to convert the numbers to the same units. Either m to cm or cm to m.
To go from meters to centimeters you multiply the number by 100.
7*100=700cm
Now you have 700cm/250cm. This needs simplified
I divided each number by 50 to get 14 and 5
14cm/5cm or 14cm:5cm
The formula for circumference is 2πr.
C = 2(3.14)(119.3)
C = 749.204
Nearest tenth would be 749.20 mm

Answer:
B(-1,-3)
Step-by-step explanation:
let the coordinates of B be (x,y)
Mid point of AB = (x₁+ x₂/2, y₁+y₂ /2)
= (-3 +x/2 , -5+y/2)
Mid point of AB is M(-2,-4)
(-3 +x/2 , -5+y/2) = (-2, -4)
-3 + x /2 = -2 ; -5+y/2 = -4
-3 + x = -2 * 2 ; -5 + y = -4 * 2
-3 + x = -4 ; -5 + y = -8
x = -4 +3 ; y = -8 +5
x = -1 ; y = -3
B(-1,-3)
