5 times sign 2+7=17 you have to times 5 and 2 and when u get the answer add it with seven
6:5 to 24:20
thats because 6 to 24 is 4 times so you do 5 times 4 and get 20.
Answer: 30
Step-by-step explanation:
Because you can break the pentagonal base into triangles and the formula to find the area of a triangle is 1/2 Bh so 840/14 = 60 divided by 1/2 = 30
A=pi r^2
then use your rate of $4.60/m^2 and multiply that by your area.
A = 3.14 (.8^2)
Cost = 2.01 m^2 $4.60/m^2 = $9.24
So your answer would be B
