Answer:

6957 inches squared

Step-by-step explanation:

surface area of a cone = πr × (r + √[h² + r²])

h = height

r = radius = 4/2 = 2 inches

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

(3.14 x 2) x (2 + √5² + 2²) = 6.28 x 7.39 = 46.38 inches squared

the amount of coated paper needed for 1 cup is 46.38 inches squared

Amount needed for 150 cups = 46.38 x 150 = 6957

A right circular cylinder has a diameter of 12 in and a height of 12 in. if water is flowing in at the rate of 4π in3 per minute

Readme [11.4K]

The rate of change of the height is $\frac{1}{9}$ in/min.

<h3>What is a right circular cylinder?</h3>

A right circular cylinder is a cylinder that has a closed circular surface having two parallel bases on both the ends and whose elements are perpendicular to its base. It is also called a right cylinder.

Volume of the cylinder = $\pi r^{2}h$

Rate of change of height is $\frac{dh}{dt}$ = ?

At any time t,

Volume, V = $\pi r^{2}h$

Since r does not change with time, then r is a constant, so,

V = $\pi (6)^{2}h$

V = $36\pi h$

Differentiate both sides with respect to time t,

$\frac{dV}{dt} = 36\pi \frac{dh}{dt}$ -------------(i)

Since $\frac{dV}{dt}$ is given as 4 $\pi$ cu.in. per min,

$4\pi = 36\pi \frac{dh}{dt}$

$\frac{dh}{dt} = \frac{4\pi }{36\pi }$

$\frac{dh}{dt} = \frac{1 }{9 }$ in/min.

Hence, The rate of change of the height is $\frac{1}{9}$ in/min.

Kingston went parasailing in the Maldives to celebrate his graduation from Stanford Medical School. He wanted to find out the le

nata0808 [166]

Answer:

The length of rope is 420 feet.

Step-by-step explanation:

Kingston flew 300 feet above the water.

Perpendicular = 300 feet

The boat driver informed him the angle of elevation from the boat to that height is typically 45.5 degrees

We are supposed tho find the length of the rope i.e. Hypotenuse

$Sin \theta =\frac{Perpendicular}{Hypotenuse}\\Sin 45.5^{\circ} = \frac{300}{Hypotenuse}\\Hypotenuse = \frac{300}{Sin 45.5^{\circ}}\\Hypotenuse = \frac{300}{0.7132}\\Hypotenuse = 420.63$

So,The length of rope is 420 feet.
