Area of a circle is multiplying pi with the radius raised to the 2nd power.

A = π r²

Diameter = 8
Radius = 8/2 = 4

A = 3.14 x 4²
A = 3.14 X 16
A = 50.24

Gabriela has an apartment that costs 30% of her monthly budget, which is $3,575. How much is her rent?
enot [183]

Answer:

Her rent is $1072.5

Step-by-step explanation:

Monthly budget: $3,575

Her rent is 30% of her monthly budget. Since 30% = 0.3, we can multiply our monthly budget with 0.3 to get 30% of it.

30% * 3575 = 0.3 * 3575 = 1072.5

Answer: $1072.5

Montano1993 [528]
Using trigonometry table :
Sine 0 = 0
Cosine 0 = 1
Tangent 0 = 0
Co-secant 0 = 1/sine 0
                    = 1/0
                    = undefined
Secant 0 = 1/cos 0
               = 1/1
               = 1 
Cotangent 0 = 1/tan 0 
                     = 1/0

Someone please help me
MariettaO [177]

Step-by-step explanation:

\frac{4}{7}x \: + \: \frac{5}{14}x \: = 39

\frac{8}{14}x \: + \: \frac{5}{14}x \: = 39

\frac{13}{14}x \: = 39

x = \frac{\cancel{39} \times 14}{\cancel{13}}

x = 3 × 14

x = 42

So, the solution of x is 42
