Answer:
Surface Area = 6.28 x 5.223 x 3 + 6.28 x 10.446 = 164 cm^2
Step-by-step explanation:
A=2πrh+2πr2
When we divide 245 by 1.5 we find 164cm^2
Answer:
The lengths of the three sides are 10 cm, 9.49 cm and 3.16 cm
Step-by-step explanation:
Let
c ------> the length of the hypotenuse of a right triangle
x -----> the length of one leg
y -----> the length of the other leg
we know that
-----> equation A (Pythagoras Theorem)
----> equation B
-----> equation C
Substitute equation B and equation C in equation A and solve for y
Find the value of x
therefore
The lengths of the three sides are 10 cm, 9.49 cm and 3.16 cm
If an event has a probability P of happening, then there is a probability of (1-P) of the event not happening.
In this case the probability of the event is p=20/69.
Then, the probability of the event not happening is:
Answer: the probability of the event not happening is 49/69.
