Answer:
50.24
Step-by-step explanation:
A = Area
Radius = 4 (The radius is half of the diameter
Diameter = 8
Pie = 3.14
A = (pie)r^2
A = (3.14)4^2
A = (3.14)16
A = 50.24
Answer:
5n-28
Step-by-step explanation:
28-6n+7(2n-8)-3n
28-6n+14n-56-3n
28+8n-56-3n
28-56+8n-3n
-28+5n
5n-28
Answer:
y = -2x+8
Step-by-step explanation:
We have 2 points so we can find the slope
m = (y2-y1)/x2-x1)
m = ( -4 -8)/(6 - 0)
= -12/6
= -2
The y intercept is 8 from the point (0,8)
The slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y = -2x+8

area of trapezium=1/2*sum of opposite sides* height of trapezium
=1/2*44*13
=22*13
=286 sq units
Hope this helps
