If we solve for radius
V=1/3pir^2h
divide both sides by pih
V/(pih)=1/3r^2
times 3 both sides
3V/(pih)=r^2
sqrt both sides
sqrt(3v/(pih))=r

so if h=10
v=300
then
sqrt(3*300/(pi*10))=r
sqrt(900/10pi)=r
sqrt(90/pi)=r
use calculator
5.35=r

can you assume that any fraction is in simplest form if either the numerator or denominator is a prime number?
vesna_86 [32]

Answer:

some occasions yes and other no for example if a fraction was 3/9 the numerator is prime but the fraction can still be simplified to 1/3 but a number were 3/5 then you wouldn't be able to simplify it

Given MTS and SQP, find sq
STALIN [3.7K]

The measure of the side SQ from the given diagram is 19/6

<h3>Similar shapes</h3>

Similar shapes are shapes that has equal length and equal side measures and angles.

From the given diagram, the measure of the sides TSis congruent to SP and the measure of MS is congruent to SQ.

Using the expression below to determine the value of x

MS/ST = SQ/SP

Given the following parameters

MS =30

ST = 10

SQ = 6x-1

SP =  3 - 2x

Substitute the given parameters into the formula to have:

30/10 = 6x-1/3-2x

Cross multiply

10(6x-1) = 30(3-2x)

Expand

60x - 10 = 90 - 60x

60x + 60x = 90 + 10

120x = 100

x = 10/12

x = 5/6

Determine the measure of SQ

SQ = 6x - 1

SQ = 5(5/6) - 1

SQ = 25/6  - 1

SQ = 19/6

Hence the measure of the side SQ from the given diagram is 19/6
