Find the volume of a cone with a base radius of 3 cm and a height of 9 cm

katovenus [111]

The volume of a cone is 84.78 cm

<u>Step-by-step explanation</u>:

<u>Given</u>:

radius = 3 cm and

height = 9 cm

<u>To Find</u>:

The Volume of a Cone

<u>Formula</u>:

The Formula for the volume of a cone is

V=πr2 *h/3

<u>Solution</u>:

V=πr2 *h/3

π value is 3.14

V= 3.14*(3)^2*9/3

V=3.14*9*3

V= 84.78 cm

Therefore the volume is 84.78 cm.

Amelia runs a farm stand that sells strawberries and peaches. Each pound of strawberries sells for $1 and each pound of peaches

ivolga24 [154]

Answer:

<u><em>14 pounds of strawberries and 42 pounds of peaches are sold</em></u>

Step-by-step explanation:

Suppose the pounds of strawberries sold are x and pounds of peaches sold are y. then

$182= x(1) + y(4)--------A

or 182= x(1) +3x(4)------- B

182=x+12x

182/13=x

x=14

Miss Hernandez has $100 to spend on parking and admission to the zoo the parking will cost $7 and Mission tickets will cost 1550

Mandarinka [93]

It should say $15.50. Parking = p. n = number of people.

n15.50 + 7 is the equation.

She can bring 6 people, because (6 * 15.50) + 7 = $100
Glad to help!

A Ferris wheel has a radius of 10 m, and the bottom of the wheel passes 1 m above the ground. If the Ferris wheel makes one comp

Volgvan

Answer: $1+10(1-\cos (\frac{\pi t}{9}))$

Step-by-step explanation:

Given

radius of wheel $r=10 m$

Time period of Wheel $T=18 s$

and $T\cdot \omega =2\pi$ , where $\omega =angular velocity of wheel$

$\omega =\frac{2\pi }{18}$

Let at any angle $\theta$ with vertical position of a point is given by

$x=r\sin \theta$

$y=y_0+r(1-\cos \theta )$

and $\theta =\omega \times t$

for velocity differentiate x and y to get

$v_x=r\cos \theta =r\cos (\omega t)$

$v_y=0+r(\sin \theta )=r\sin (\omeag t)$

Height at any time t is given by

$h=1+10(1-\cos \theta )=1+10(1-\cos (\frac{\pi t}{9}))$
