Yeah sure absolutely.
So the volume of a cone can be calculated with $V= \pi r^{2} \frac{h}{3}$ , you can substitute values into this like the following $V = 3.14$ × $12^{2}$ <span>× </span> $\frac{8}{3}$ , which is equal to $1205 cm^{3}$

The radius of a circular box is 21 centimeters. What is the circumference of the box? A 66cm B 132cm C 176cm D 1386cm

Ulleksa [173]

The answer would be 132 because the formula for find circumference while using radius is 2(3.14)r .

C= 2(3.13)21

C= 6.28 • 21 = 131.88

131.88 rounded is 132

3,000 is 10 times as much as

nalin [4]

3,000 is 10 times as much as

3000 = 10 times of what number

We need to find 10 times what number gives us 3000

Let the unknown number be x

3000 = 10 times x

3000 = 10x

To solve for x, we divide by 10 on both sides

$\frac{3000}{10}=\frac{10x}{10}$

300 = x

So, the unknown number is 300

3000 = 10 times 300

3000 is 10 times as much as 300

The diagonal in a rectangle is 20 units long, and the angle between the diagonal and a side is 36º 42'.

mylen [45]

Side adjacent to the given angle: x
Diagonal=hypotenuse=20
cos (36° 42') =(side adjacent to angle 36° 42')/Hypotenuse
cos (36° 42')=x/20
Solving for x. Multiplying both sides of the equation by 20:
20 cos (36° 42')=20 (x/20)
20 cos (36° 42')=x
x=20 cos (36° 42')
x=20 (0.801775644)
x=16.03551288
x=16.04

Answer: Option D. 16.04
