74 degrees, because angle 1 and 8 add up to 73 degrees, so to make 180 you subtract 180-73 degrees, which makes 112 degrees for angle 9. Angle 9 and 12 are supplementary so they should both add up to 180. That means that angle 12 must be 68. Angles 12, 7, and 6 must add up to 180, so 38+68=106. 180-106=74. Therefore, angle 6 is 74 degrees

You have been asked to design a can shaped like right circular cylinder that can hold a volume of 432π-cm3. What dimensions of t
rosijanka [135]

Answer:

Height = 12cm

Radius = 6cm

Step-by-step explanation:

Given

Represent volume with v, height with h and radius with r

V = 432\pi

Required

Determine the values of h and r that uses the least amount of material

Volume is calculated as:

V = \pi r^2h\\

Substitute 432π for V

432\pi = \pi r^2h

Divide through by π

432 = r^2h

Make h the subject:

h = \frac{432}{r^2}

Surface Area (A) of a cylinder is calculated as thus:

A=2\pi rh+2\pi r^2

Substitute \frac{432}{r^2} for h in A=2\pi rh+2\pi r^2

A=2\pi r(\frac{432}{r^2})+2\pi r^2

A=2\pi (\frac{432}{r})+2\pi r^2

Factorize:

A=2\pi (\frac{432}{r} + r^2)

To minimize, we have to differentiate both sides and set A' = 0

A'=2\pi (-\frac{432}{r^2} + 2r)

Set A' = 0

0=2\pi (-\frac{432}{r^2} + 2r)

Divide through by 2\pi

0= -\frac{432}{r^2} + 2r

\frac{432}{r^2} = 2r

Cross Multiply

2r * r^2 = 432

2r^3 = 432

Divide through by 2

r^3 = 216

Take cube roots of both sides

r = \sqrt[3]{216}

r = 6

Recall that:

h = \frac{432}{r^2}

h = \frac{432}{6^2}

h = \frac{432}{36}

h = 12

Hence, the dimension that requires the least amount of material is when

Height = 12cm

Radius = 6cm

<h2>○=> <u>Correct option</u> :</h2><h2>\color{hotpink}\bold{ (a) \: 130}</h2><h3>○=> <u>Steps to derive correct option</u> :</h3>

Angle (p+7)° and angle (3p+1)° are a linear pair so their sum will be equal to 180°.

Which means :

=\tt 3p + 1 + p + 7 = 180

Let us solve that equation to find the value of p and the two angles :

=\tt 3p + 1 + p + 7 = 180

=\tt 3p + p + 1 + 7 = 180

=\tt 4p + 8 = 180

= \tt4p = 180 - 8

= \tt4p = 172

=\tt p =  \frac{172}{4}

\hookrightarrow \tt  \color{plum}p = 43

Thus, value of p = 43

Measure of angle (p+7)° :

=\tt 43 + 7

\tt\color{plum}angle \: (p + 7)° =\tt 50°

Measure of angle (3p+1)° :

=\tt 43 \times 3 + 1

= \tt129 + 1

\tt\color{plum}angle \: (3p + 1)° = 130°

Thus, the measure of the larger angle = 130°

Therefore, the correct option is <em>(a) 130</em>
