Answer:
6
Step-by-step explanation:
Here, we are told to find the length of EB
Since the chords AB and CD are both 5 units(equidistant) away from the center of the circle, then we can conclude that they are both congruent and thus are equal in length
Now we use a circle theorem to solve for the length EB
The theorem is that a line that joins the center of a circle to a chord makes a perpendicular angle with the chord and splits the chord into 2 equal parts.
Now we can say that; AB = AE + EB so we split 12 into 2 which is 6 units and that is the length of EB
Answer:
C = 50.24
A = 7,925.540864 (Round to whatever you want)
Step-by-step explanation:
c = 2πr
c = 2(3.14)(8)
c= 50.24
A = πr^2
A = (3.14)(50.24)^2
A = 7,925.540864
Answer:
B and D
Step-by-step explanation:
This is because for B you do 8x9x1 which is basically 8x9 which is 72. Then, for D you do 12x3x2. Do 3x2 first and you get 6. Then, do 6x12 which is also 72. So the correct answers that will give you the volume of 72 units cube is B and D. Hope this helps!
45 - 20 =??? and for the other 1... 1,400 + 7,437 = ???
