Plug in the values into the base equation; 

l=2 \pi r(  \frac{ \alpha }{360} ) <-- alpha is the degree 

l=2 \pi (12)(9/360) 
l=1.88495 ft ≈ 1.90 ft 

Hope I helped :)

Can someone please help me with this :(
mrs_skeptik [129]

Answer:

first find the surface area of one of the square and one of the triangle.

then multiple it by the number of square and triangle they have

finally add the total surface area of the triangle with the total surface area of the square.

Step-by-step explanation:

  1. for one square

area= base * width

= 10*10

=100

total area of square= number of square * area of one square

t=6*100

t=600

  • for one triangle

area = 1/2 base * height

= 1/2 *10*8.66

=43.3

total area of triangle=number of triangle* area of one triangle

t2=8*43.3

=346.4

total surface area= total surface area of the square+ total surface area of the triangle

=600+346.4

=946.4 in^2
