Answer:

The area needed is 13,000 square feet.

Step-by-step explanation:

The total space (area) = area of the square + area of the two half circles

=> Total area = area of square + area of the circle (as adding the two halves makes a complete circle)

$i.e \\ total \: area \: = 51 \times 250 + \pi( {r}^{2} ) \\ total \: area \: = 12750 + \pi( {25.5}^{2} ) \\ total \: area \: = 12750+ 251 \\ total \: area \: = 13000 \: square \: feet$

La familia Sánchez Olguín, quiere terminar de construir su casa y necesita S/.25000 para todos los gastos del acabado de la casa

erastova [34]

Extraemos los datos del problema:

Capital Inicial → C₀ = S/.25000
Interés bimestral → i = 8 % = 0.08
Periodos → n = 3

<h2 /><h2>Bimestre 1:</h2>

Capital Inicial Bimestre → C = S/.25000

Tasa de interés bimestral:

I = C×i

I = S/.25000 × 0.08

I = S/.2000

Monto final:

M = C + I

M = S/.25000 + S/.2000

M = S/.27000

Variación Porcentual:

% = (M - C₀) / C₀

% = ( 27000 - 25000) / 25000

% = 8

<h2>Bimestre 2:</h2>

Capital Inicial Bimestre → C = S/.27000

Tasa de interés bimestral:

I = C×i

I = S/.27000 × 0.08

I = S/.2160

Monto final:

M = C + I

M = S/.27000 + S/.2160

M = S/.29160

Variación Porcentual:

% = (M - C₀) / C₀

% = ( 29160 - 25000) / 25000

% = 16.64

<h2>Bimestre 3:</h2>

Capital Inicial Bimestre → C = S/.29160

Tasa de interés bimestral:

I = C×i

I = S/.29160 × 0.08

I = S/.2332.8

Monto final:

M = C + I

M = S/.29160 + S/.2332.8

M = S/ 31492.8

Variación Porcentual:

% = (M - C₀) / C₀

% = ( 31492.8 - 25000) / 25000

% = 25.97

Keep answers as exact as possible (NOT IN TERMS OF PI). <br><br>

Andreyy89

Answer:

121.9

Step-by-step explanation:

I will use pi but not in the answer

use formula V=πr²h

(π)(3.5²)(5.5)

12.25 × 5.5=67.375 × π=211.6648...

1/2(4/3(π(3.5³))

4/3(42.875)=57.166...× π = 179.59438...

1/2(179.59438...) = 89.79719...

211.6648... - 89.79719... = 121.86761... ≈ 121.9
