The volume of the sphere is 904.32 m. To the nearest meter, what is the radius of the sphere????? Use 3.14 for pi.

Rus_ich [418]

Answer:

Step-by-step explanation:

The formula for the volume of a sphere is $\frac{4}{3} \pi r^3$ . Plugging in the values that you are given, you get:

$904.32=\frac{4}{3}\pi r^3$

Dividing both sides by pi or 3.14:

$288=\frac{4}{3}r^3$

Dividing both sides by 4/3:

$216=r^3$

Taking the cube root of both sides:

$r=6$

Hope this helps!

If the diameter of a circle is 5 centimeters, how long is the arc sub tended by an angle measuring 60 degrees?

jenyasd209 [6]

Answer:

3/5pi

Step-by-step explanation:

The formula of getting the arc length is

arc length = angle * pi / 180 * r

arc length = 60 * pi / 180 * 5

arc length = 300 * pi / 180

arc length = 5pi / 3

110 freshmen participated in sports or clubs or both. 55 are involved in sports and 68 are involved in clubs. How many students

Varvara68 [4.7K]

Answer: 42

Step-by-step explanation:

Let A represents the number of freshmen participated in sports and B represents the number of freshmen participated in clubs.

Then , we have given that

$n(A)=55\\\\n(B)=68\\\\n(A\cup B)=110$

Using formula

$n(A\cup B)=n(A)+n(B)-n(A\cap B)$

We have,

$110=55+68-n(A\cap B)\\\\\Rightarrow\ n(A\cap B)=123-110=13$

Now, the number of students are involved in just sports is given by :-

$n(A)-n(A\cap B)=55-13=42$

Hence, 42 students are involved in just sports.
