Answer:
D. 1662 cm
Step-by-step explanation:
A=πr2=π•23≈1661.90251cm²
which is 1661.9
but of course you have to round up for 1662 cm :)
Responda:
11
Explicação passo a passo:
Área do retângulo = comprimento * largura
Dado
Comprimento = 4
Largura = 3x + 2
Área = 44
Substitua na fórmula e obtenha x
44 = 4 (3x + 2)
44 = 12x + 8
12x = 44-8
12x = 36
x = 36/12
x = 3
Obtenha os lados mais longos
Lado mais longo = 3x + 2
Substitua x = 3
Lado mais comprido = 3 (3) + 2
Lado mais comprido = 11
Portanto, a medida do lado mais longo deste retângulo é 11
First you want to find the area of the square, which would be 121. ( 11 x 11 )
Next you want to find the area of the circle, 78.54 ((pi)5^2)
Last, you want to subtract the area of the circle, from the area of the square that is shaded. Youre left with 42.46
Hope this helped
It would be $27.96 because if you take half of 18.64 and add that answer to 18.64 you would get the total
for 6 pounds
