Answer:
6 and 15
Step-by-step explanation:
First, you would find the area of the rectangle using the formula A = L • W, which would then give you 24 cm2. Then you would find the area of the triangle using the formula A = bh1/2, which would the give you the answer of 8 cm2. Then you would have to find the area of the semi-circle, using the formula A = (r • r) • 3.14 / 2, which would then give you the answer of 25.12 cm2. Finally, you would have to add up all three area’s, so 25.12 + 8 + 24, which would then give you the final answer, which would be 57.12 cm2.
Answer:
C
Step-by-step explanation:
This is actually a combination problem as we are trying to select groups of 5 from the 15 qualified trainees.
To do this, we use the combinatorial approach. This is done by using the formula 15C3 = 15!/(15-3)!3!
This gives a value of 455
