Answer:
14.45cm2
Step-by-step explanation:
The diagonal is the diameter of the circle.
4.6cm
The perimeter of the circle is
Pi x4.6= 3.142 * 4.6= 14.45cm2
3/4=x/60 so you divide 60 by 4 and get 15x3=45/60
Answer:
24
Step-by-step explanation:
let 'x' = number
x/2 - 2 = 10
add 2 to each side to get:
x/2 = 12
cross-multiply to get:
x = 24
Answer:
-3
Step-by-step explanation:
Use slope formula to find the slope of the first road:
(y2 - y1) / (x2 - x1)
(1 - 5) / (-1 - 11)
-4 / -12
1 / 3
The slope of a line perpendicular to this line would just be the negative reciprocal of the slope:
-3 / 1 or just -3
