What is the exact volume of a sphere with a diameter of 18 cm?<br> ______ cm3
madam [21]
The formula to find the volume of a sphere is: V= \frac{4}{3}  \pi r^{3}
Since the diameter is 18 cm, so the radius is equal to r=18/2 = 9
Now we replace r by it's value, so we get: 
\frac{4}{3} \pi  9^{3}
\frac{4}{3}  \pi 729
972 \pi
And we get approximately 3053.63  cm^{3}
Hope this Helps :D

(03.01 LC)<br><br> What is the length of leg y of the right triangle? (1 point)
EastWind [94]

Answer:

<h2>A</h2>

Step-by-step explanation:

The complete question is

What is the length of leg y of the right triangle?

A right triangle with hypotenuse 26 and legs 24 and y

  • 10
  • 14
  • 24
  • 26

We need to use the Pythagorean Theorem, where h=26 and x=24,

h^{2} =x^{2} +y^{2}\\ 26^{2}=24^{2}+y^{2}\\y=\sqrt{26^{2}-24^{2}}\\ y=\sqrt{676-576}\\ y=\sqrt{100}\\ y=10

Therefore, the right answer is A. The length of the missing leg is 10 units.

<h2>Explanation</h2>

<u>we know that</u>

geometric sequence 8, 16, 32

<u>the </u><u>question</u><u> </u><u>is</u>

the 8th term

<u>the </u><u>answer </u><u>is</u>

first we have to find the ratio

\sf r=  \frac{ U_2}{U_1}  \\  \sf r=  \frac{ 16}{8} \\  \sf r = 2

than, we have to find the 8th term

\sf U_n = ar^{n-1} \\ \sf U_8 = 8 \times 2^{8-1} \\ \sf U_8 = 8 \times 2^7 \\ \sf U_8 = 8 \times 128 \\ \bold {\sf U_8 = 1024}
