Answer:
Yes.
Step-by-step explanation:
The triangle inequality theorem states that in order for something to be a triangle, any of it's two sides added together must be greater than the remaining side. Because 4 and 5 are the shortest sides and they satisfy the triangle inequality theorem, you can form a triangle.
Answer:
C = 60pi cm or approximately 188.4 cm
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
C = 2* pi * 30
C = 60 pi
We can approximate pi by 3.14
C is approximately 60*3.14 or 188.4
