Answer:
49.9348634
Step-by-step explanation:
pi r squared is area of a circle
4ft squared = 16ft
16 pi is area of circle face
250 / 16pi = 49.9348634 (round to whatever you need)
The probabillity can be found by using binomial probability formular considering that the event is discrete in nature and there are two possiple outcomes.
Answer:
not sure but i think its b
Step-by-step explanation:
(i) XYZ = 180 - 64
= 116 degrees
Opposite angles in a cyclic quadrilateral add up to 180 degrees
(ii) YXZ = 23 degrees
Alternate angles in a segment are the same
(iii) OXZ = 26
XOZ = 64 x 2
= 128 degrees
The the angle at the centre is double the angle at the circumference.
180 - 128 = 52
OXZ = 52/2
= 26
Triangle OZX is an isosceles triangle

Answer:
The point is located at (0,7) is correct
The point is on the y-axis. is correct
Step-by-step explanation:
The point is located at (7,0). is wrong because first the x values comes and then y values come here the x value is 0 and y value is 7
The point is on the x-axis.this is also wrong as you can see that the point lies on y axis not x axis
