Answer: $45781.2\text{ cm}^3$

Step-by-step explanation:

From the given picture, the diameter of the base of cylinder = 12 cm

i.e. the radius of the cylinder = $r=\dfrac{12}{2}=6\ cm$

Height = 15 cm

If the dimensions of the following cylinder are tripled, then the radius of cylinder = $3\times6=18\ cm$

Height= $3\times15=45\ cm$

We know that the volume of a cylinder is given by :-

$\text{Volume}=\pi r^2 h\\\\\Rightarrow\\text{Volume}=(3.14)(18)^2(45)\\\\\Rightarrow\text{Volume}=45781.2\text{ cm}^3$

almond37 [142]

Answer: 40.

Step-by-step explanation:

Given : The sweater department ran a sale last week and sold 95% of the sweaters that were on sale.

95% can be written as 0.95 [ by dividing 100 ]

Also, the number of sweaters sold = 38

Let x be the number of sweaters were on sale.

Then , we have the following equation :_

$0.95x=38\\\\\Rightarrow\ x=\dfrac{38}{0.95}=\dfrac{3800}{95}=40$

Hence, 40 sweaters were on sale.

The length is one inch more than the width, which is one inch more than the height. The volume is

Romashka-Z-Leto [24]

Answer:

V = ( 2 +H ) × ( 1 +H ) × H = (2 + 3H + H² ) unit³

Step-by-step explanation:

according to question :

Let the Height be = H unit

The measure of width = (1 inch + H) unit

The measure of length = 1 inch + width =( 1 inch + 1 inch + H) unit = (2 + H) unit

So, the volume V = Length × width × Height

Or, V = ( 2 +H ) × ( 1 +H ) × H = (2 + 3H + H² ) unit³ Answer

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant. The correct option is B.

<h3>What is a circle?</h3>

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.

Given the measure of arc, RS is (2 x + 8) degrees, the measure of arc R U is (3 x minus 14) degrees, and the measure of arc U T is (3 x minus 14) degrees.

(3x-14)° + (3x-14)° + (2x+8)° = 180°

8x -20 = 180

8x = 200

x = 25

Hence, the correct option is B.
