The area equation for a rectangle is length times width. And the area equation for a half (or semi) circle is (1/2) times pi (or 3.14) times the radius squared.
So, you have to add the area of the rectangle and semi-circle together.
Rectangle: A = 18*10 = 180 cm^2
Semi-circle: A = (1/2)*3.14*(18/2)^2 = 127.17 cm^2
Add those together to get 307.17cm^2 or choice C.
-3/4 is the answer.
First you must make all the denominators the same = 9/4 = 9/4, 6/1 (mulitply both sides by 4) = 24/4, 3/1 (multiply both sides by 4) = 12/4. So we come out with 9/4 - 24/4 +12/4.
Then solve. 9/4 - 24/4 +12/4 = -3/4
Answer:
D
Step-by-step explanation:
The other graphs are functions.
Graph A is a linear function, and C is an Absolute Value Function.
Graph B also seems to be a function.
However- I can only narrow it down to B or C. I apologize if my answer is not correct.
If two planes intersect there’s alway going to be an intersection point where the two cross over
