If an orange traffic cone has a diameter of 10 in. and a height of 28 in. what is the volume of the cone?

e-lub [12.9K]

Answer:

$\large\boxed{V=\dfrac{700\pi}{3}\ in^3\approx732.67\ in^3}$

Step-by-step explanation:

The formula of a volume of a cone:

$V=\dfrac{1}{3}\pi r^2H$

r - radius

H - height

We have the diameter 2r = 10in → r = 5in, and the height H = 28in.

Substitute:

$V=\dfrac{1}{3}\pi(5^2)(28)=\dfrac{1}{3}\pi(25)(28)=\dfrac{700\pi}{3}\ in^3$

$\pi\approx3.14\to V\approx\dfrac{(700)(3.14)}{3}\approx732.67\ in^3$

Find the exact circumference of a circle with an area equal to 36 sq. in.

DochEvi [55]

The area of the circle is determined through the equation,
A = πr²
Plug in the value of area
36 in² = πr² ; r = 3.385 in
The formula for the circumference of the circle is,
C = 2πr
Substitute the value of radius,
C = 2π(3.385 in) = 6.77π in
Thus, the circumference of the circle is 6.77π inches.

If arctan(3/5)=K Tan(k)=?

hichkok12 [17]

$arctan(x)=y$

this function is the inverse function of tan...

$arctan(x)=tan^{-1}(x)$

then...

$x=tan(y)$

in this case

$arctan(\frac{3}{5})=K$

$\frac{3}{5}=tan(K)$

$\boxed{\boxed{tan(K)=\frac{3}{5}}}$
