C = 2πr
6.28 = 2(3.14)(r)
6.28 = 2(3.14r)
6.28 = 6.28r
6.28 6.28
1 = r
A = πr²
A = (3.14)(1)²
A = 3.14(1)
A = 3.14 units²

Answer:
b and c
Step-by-step explanation:
The Triangle Inequality Theorem lets us know that the sum of the two shortest sides of the triangle must be greater than the third side of the triangle.
In both A and D, the sum of the shortest two sides are equal to, not greater than the third side, so they will not form a triangle.
In B, 12+20 is 32, which is greater than 25. And in C, 18+24 is 42, which is greater than 30, so they both will form a triangle.
Answer:
P = 1.5x.
Step-by-step explanation:
Let the length of each side of the first triangle be x, then
Perimeter of this triangle
= 2x + 1.5x
= 3.5x.
So perimeter of smaller triangle is:
P = 1/2 * 3.5x
P = 1,.5x.
