Answer:
The value of x is equal to ![5](https://tex.z-dn.net/?f=5)
Step-by-step explanation:
we know that
The diameter divide the circle into two equal parts
In this problem
MO=NO
substitute the values
![5x-7=18](https://tex.z-dn.net/?f=5x-7%3D18)
solve for x
Adds 7 both sides
![5x=18+7](https://tex.z-dn.net/?f=5x%3D18%2B7)
![5x=25](https://tex.z-dn.net/?f=5x%3D25)
Divide by 5 both sides
![x=25/5=5](https://tex.z-dn.net/?f=x%3D25%2F5%3D5)
The answer is 4pi because the formula to find the circumference is C = 2 pi r. this question is asking for the terms of pi which means you remove the pi from the formula and solve it with out it. the radius is 2 because of the 2 units on the graph is halfway of the circle. you would just multiply 2 x 2 and get 4. after that you put the pi on the end of the 4. so the answer is C. (4pi)
Imagine a big solid and you cut out that one piece
the big solid is 9 by 12 by 3+4 (LWH)
so the volume is 9*12*7=756 cubic cm
the small slolid is 6 by 4 by 12 or 288 cubic cm
big-small=756-288=468 cubic cm
the volume is 468 cubic cm
Answer:
If the dimension increased by doubled, tripled or quadrupled, then it will be 2x, 3x, or 4x for each dimension.
Answer:
18/81
Step-by-step explanation:
the current fraction adds up to 11 so to get 99 you would need to multiply both the numerator and the denominator by 9 to get a sum of 99
so 2 x 9 = 18 and 9 x 9 =81
so answer is 18/81
