Answer:
71.13
Step-by-step explanation:
The half area of a circle is A = 1/2 * pi*r^2 = 1/2 * pi * 3^2 or 9
The trapezoid is a rectangle and a triangle. Rectangle is 8*6 and the triangle is 6*(11 - 8) * 1/2
The total is 1/2 * pi * 9 + 8*6 + 6*(11 - 8) * 1/2 = 71.13
Answer:
Step-by-step explanation:
If 60% failed then 40% passed
.4n=500
n=1250 so there are 1250 candidates of which
.6(1250)=750 failed
So 750 candidates failed.
Ohhh it might be...
R = d/t
tr = d
/r /r
t = d/r

Step-by-step explanation:
The answer is in attached picture
To simplify that equation you would first subtract 8 from both sides, getting 7x=28. You would then divide both sides by 7, getting x=4.
