Help!! Thank you so much!!

The volume we're looking for is the volume of both cones in the figure.

The volume of a cone is $V=\pi r^2\frac{h}{3}$ .

So, $V_{tot} = V_{1} + V_2$ .

<u>Cone 1's variables:</u>

r = 2.6

h = 5

<u>Cone 2's variables:</u>

r = 2.6

h = 3

Now we can just plug and chug!

$V_{tot} = [(3.14)(2.6^2)(\frac{5}{3} )] + [(3.14)(2.6^2)\frac{3}{3} )]\\V_{tot} = [(3.14)(6.76)(1.67)] + [(3.14)(6.76)(1)]\\V_{tot} = (35.45) + (21.23)\\V_{tot} = 56.68$

V = c. 56.6 cubic units

The perimeter of a triangle is 65 cm. The

$▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪$

The longest side measures :

$27\: \: cm$

<h3> $\large \boxed{ \mathfrak{Explanation}}$ </h3>

Perimeter of a triangle is equal to sum of measures of its all three sides, that is :

$x + x + 8 + x + 12$

and according to the question, the perimeter of the triangle is = 65 cm

so, let's equate both the expressions to find value of x :

$x + x + 8 + x + 12 = 65$
$3x + 20 = 65$
$3x = 65 - 20$
$3x = 45$
$x = 45 \div 3$
$x = 15$

The longest side of the Triangle is :

$x + 12$
$15 + 12$
$27 \: \: cm$
