Answer: 55,425.2 cm3
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a hemisphere = 2/3 π radius^3
Replacing with values given and solving for V (volume)
V = 2/3 π (29.8) ^3 = 55,425.2 cm3
In conclusion, the volume of the hemisphere is 55,425.2 cubic centimeters.
Feel free to ask for more if needed or if you did not understand something.
Answer: 60
Step-by-step explanation:
Answer:
circumference of the base
Step-by-step explanation:
Given that
The height of the cylinder is 10 inches
And, the 8 inches show the circumference of the base or the circumference of the circle
So,
C = 2r π
or
8 = 2r π
So, the 8 inches represent the same as shown above
Hence, the last option is correct
Answer: D
Step-by-step explanation:
Yeah, lets look at each of the functions. I'll refer to them as A, B, C, D, and E.
A) f(x)=x^2-16
This has two zero. x^2-16= (x+4)(x-4), which two zeroes include -4 and 4.
Here we introduce an important concept, if the function isn't a perfect square, and is a quadratic, it has two zeroes.
B) This is linear, so it obviously has 1 zero.
C) Two zeroes, because it isn't a perfect square.
D) x^2-10x+25 = (x-5)^2, so it has only one zero.
E) Not a perfect square, so two roots.
