Answer:19
Step-by-step explanation:
Subtract then add
Circumference of circle = pi*diameter = 13pi cm
Area is pi*d^2/4 = pi*13^2/4 = 42.25pi cm^2.
You need to find the area of the hexagon, and the area of the triangle.
The formula for the area of a triangle is

I hope this helps you a little.

Step-by-step explanation:
First find the slope
m= ( y2-y1)/(x2-x1)
= (-5- -7.5)/ ( 2 - -3)
= (-5+7.5) / ( 2+3)
= 2.5 /5
=1/2
Then using the slope intercept equation of a line
y = mx+b where m is the slope and b is the y intercept
y = 1/2x+b
Using a point from above
-5 = 1/2(2) +b
-5 =1+b
Subtract 1 from each side
-6 = b
We have the y intercept
y = 1/2x-6
Tahlia forget to find the y intercept for the equation
Answer:
24
Step-by-step explanation:
If we say there are 5x maple trees there are 3x oak trees. We know there 6 more maple than oak so we can say 5x = 3x + 6. This means 2x = 6 so x = 3.
This means there are 5*3=15 maple trees and 3*3=9 oak trees so there are 15+9=24 in total.
