Calculate the area of this figure to the nearest hundredth. Use 3.14 to approximate pi
Flura [38]

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

The ratio of the number of boys to the number of girls in a dance club is 5 : 6. After 6 more boys join the club, the ratio beca
UkoKoshka [18]

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
