The formula for the volume of a sphere is:

V = 4/3 * PI * r^3

The diameter is given as 21.6, divide this by 2 for the radius:

R = 21.6 / 2 = 10.8

V = 4/3 * PI * 10.8^3

V = 5276.7 cm^3


The answer is D

Answer:

D) 5276.7 cm3

Step-by-step explanation:

Volume of a sphere is given by

V = 4/3 *pi*r^3

We are given the diameter.  The diameter is twice the radius

d =2r

21.6 = 2*r

21.6/2 = 2r/2

10.8 =r

Now we can find the volume,

V = 4/3 * pi *(10.8)^3

V =5276.669286

Pretest: Unit 1
Alex_Xolod [135]

A vertical line that the graph of a function approaches but never intersects. The correct option is B.

<h3>When do we get vertical asymptote for a function?</h3>

Suppose that we have the function f(x) such that it is continuous for all input values < a or > a and have got the values of f(x) going  to infinity or -ve infinity (from either side of   x = a) as x goes near a, and is not defined at   x = a, then at that point, there can be constructed a vertical line  x = a and it will be called as vertical asymptote for f(x) at   x = a

A vertical asymptote can be described as a vertical line that the graph of a function approaches but never intersects.

Hence, the correct option is B.

Answer:

A  ≈ 35.3 units²

Step-by-step explanation:

Calculate the radius CB using Pythagoras' identity in the right triangle.

CB² + AB² = AC²

CB² + 6² = 9²

CB² + 36 = 81 ( subtract 36 from both sides )

CB²  = 45 = r²

Then area of quarter circle is

A = \frac{1}{4} × πr² = \frac{1}{4} × π × 45 ≈ 35.3
