Answer:
25.
Step-by-step explanation:
I am assuming you only mean the small triangles, not the composite ones.
The second triangle set has 3 triangles on bottom row and 1 on the top - total 4.
The 3rd triangle set has 5 triangles on the bottom , 3 on the next up and 1 on the top - total 9
Following the pattern 4th set will have the number of triaNGLES
7 + 5 + 3 + 1 = 16.
So the 5th will have 9 + 7 + 5 + 3 +1 = 25 triangles.
Answer:
#1. 31.4 square units
Step-by-step explanation:
We are solving for the square units and also we are circumference formular
which is C = R x 2) (3.14)
R is 5 but in a case they don't give us the Radius and gives us the Diameter we decide the Diameter by 2 and we will get the radius.
Back to the problem
C = R x 2) (3.14)
C = 5 x 2 x 3.14
C = 10 x 3.14
C = 31.4
Answer: $1.44
