Roman55 [17]

Answer:

<u>65.4 cubic inches</u>

Step-by-step explanation:

Formula for the volume of a cone :

<u><em>Volume (cone) = 1/3πr²h</em></u>

=============================================================

Given :

⇒ diameter = 5 in. → radius = <u>2.5 in.</u>

⇒ height = <u>10 in.</u>

<u />

===========================================================

Solving :

⇒ Volume (cone) = 1/3 × π × (2.5)² × 10

⇒ Volume (cone) = 62.5π/3

⇒ Volume (cone) = <u>65.4 cubic inches</u>

Solve the math problem

zalisa [80]

Answer:

$\frac{4w {}^{8} }{9m {}^{4} }$

Step-by-step explanation:

separate with like terms

$\frac{4}{9} , \: \frac{w {}^{9} }{w} \: and \: \: \frac{m {}^{5} }{m {}^{9} }$

the first fraction can be left alone as it can't be simplified any further

the second fraction can be written as w⁹ ÷ w¹ , when the bases are the same and division is involved subtract the powers: 9 - 1 = 8, so it's simplified to w⁸

the third fraction can be written as m⁵ ÷ m⁹, subtract the powers: 5 - 9 = -4, so it's simplified to m⁻⁴

${m}^{ - 4} = \frac{1}{m {}^{4} }$

putting it together:

$\frac{4w {}^{8} }{9m {}^{4} }$
