Answer:
49.12 ft^2
Step-by-step explanation:
We can add the areas of the two figures
We have a triangle
A = 1/2 bh
A = 1/2 (6)(8)
A = 24
We have 1/2 of a circle so find 1/2 of the area
A = 1/2 ( area of a circle)
= 1/2 ( pi r^2)
The diameter is 8 so the radius is 4
= 1/2 ( 3.14 * 4^2)
= 25.12
Add the areas together
24+25.12 = 49.12
44
Step-by-step explanation:
let boys be x and girls be y
x/y=5/6
x=5y/6....(1)
if 6 boys join the club that will be x+6
Therefore:
(x+6)/y=13/12
13y=12x+72
13y-12x=72
Recall x=5y/6
Therefore:
13y-12(5y/6)=72
13y-(2*5y)=72
13y-10y=72
3y=72
y=24 people
Therefore:
x=(5*24)/6
x=20 people
Therefore people in the club before are 20+24=44
