Circumference of circle = π × Diameter
= π × 18 cm
= 56.54867 or 56.54 to 1 dp
To find the area of the triangle, you use the formula A=bh/2. This gives you the area of 49in^2 for the triangle, eliminating choices C and D. The area of the entire square is 14^2, or 196in^2, which gives us 4 when divided by the area of the triangle, 49in^2. Therefore, the answer is B, or that the area of the triangle is 49in^2 so she can create only 4 triangles.
Complementary angles add up to 90o.
The complement of 21 is 90 - 21 = 69
