Answer: 4. 432 cm^2/2 = 216 cm^2
6. 309.76 mm^2
8. pi * 22^2 = 484pi (or, approximately 1,519.76) in^2
484/2 = 242pi or 759.88 in^2.
10. 297.84 in^2/2 = 148.92 in^2
Step-by-step explanation:
To find the area of a triangle, you take the base and multiply by the height, and then divide by 2. Hence giving me the answers I obtained in #4 and #10.
A square is equal on all sides, so you would just square the measurement of the one side.
To find the area of a circle, you would do pi times the radius^2. Since this is a semicircle, you actually should divide the number you got by 2. (Which is why I did so up above).
Answer:23
Step-by-step explanation:
Answer:
5 is the only one wrong.
Step-by-step explanation:
It Should be 1/3 because there are 2 chances out of 6 possibilities.
2/6 = 1/3
Basically we have to calculate P X < 0.95. By using the normal distribution formula for any random variable we can get our answer.
SO first from z table we will have to check the corresponding z value from the table. After we get that value we can do X - mean / the std dev = that particular value that i am naming A.
SO X - 5 / 0.5 = A. Now we can solve X for our answer.
Yes you has the right answer because they are congruent triangles which means the has congruent sides
