Answer:

243 m²

Step-by-step explanation:

<u>Area of circle:</u>

A = πr²

<u>Circumference of circle:</u>

C = 2πr

<u>Given</u>

C = 55 m

<u>Find r using the second formula:</u>

2πr = 55
2*3.14r = 55
r = 55/6.28
r = 8.8 (rounded)

<u>Find area using the first formula:</u>

A = 3.14*8.8²
A = 243 m² (rounded)

Solve the following equation; domain 0< x < 360; 3 cot x + sqrt 3 = 0

kondaur [170]

ANSWER

$x =120 \degree \: or \: 300 \degree$

EXPLANATION

We want to solve the trigonometric equation

$3 \cot(x) + \sqrt{3} = 0$

We group like terms to obtain,

$3\cot(x) = - \sqrt{3}$

Divide both sides of the equation by 3 to get,

$\cot(x) = - \frac{ \sqrt{3} }{3}$

We can reciprocate both sides to get,

$\tan(x) = - \frac{3}{ \sqrt{3} }$

We simplify the right hand side to get,

$\tan(x) = - \sqrt{3}$

Since the tangent ratio is negative, it implies that it is either in the second quadrant or fourth quadrant.

In the second quadrant,

$x = 180 \degree - arctan( \sqrt{3})$

$x = 180 \degree - 60 \degree = 120 \degree$

In the fourth quadrant,

$x = 360 \degree - arctan( \sqrt{3})$

$x = 360 \degree - 60 \degree$

$x = 300 \degree$

One smaller cube labeled with fish food with dimensions of one-quarters feet on each side. Larger cube labeled shipping box with

jarptica [38.1K]

Answer:

Given: Length of smaller cube= 1/4 feet each side

Length of larger cube= 3.75 feet

Width of larger cube= 3 feet

Height of larger cube= 3.25 feet

Step-by-step explanation:

Volume of a cube= length * width * height

Volume of a larger cube= 3.75 * 3 * 3.25 cubic foot

Volume=36.5625 cubic foot

Volume of smaller cube= length * length * length (as length is same on each side)

Volume of smaller cube= 1/4 * 1/4 * 1/4

Volume of smaller cube= 1/64 cubic foot

Hence, volume is calculated.
