Answer:

528 cm²

Step-by-step explanation:

curved surface area of cylinder= 2\pi rh, where h is the height of the cylinder and r is the radius of the base.

Given that the radius is 14cm, r= 14.

Curved surface area of cylinder

= 2( \frac{22}{7} )(14)(6) \\  = 528 \: cm^{2}

Dos cuadrados de lado
Kaylis [27]

La franja amarilla del rectángulo tiene un área de 30 centímetros cuadrados.

<h3>¿Cuál es el área de la franja amarilla del rectángulo?</h3>

En este problema tenemos un rectángulo formado por dos cuadrados que se traslapan uno al otro. La franja amarilla es el área en la que los cuadrados se traslapan. La anchura del rectángulo es descrita por la siguiente ecuación:

(10 - x) + 2 · x = 17

Donde x se mide en centímetros.

A continuación, despejamos x en la ecuación descrita:

10 + x = 17

x = 7

Ahora, el área de la franja amarilla se determina mediante la fórmula de area de un rectángulo:

A = b · h

Donde:

  • b - Base del rectángulo, en centímetros.
  • h - Altura del rectángulo, en centímetros.
  • A - Área del rectángulo, en centímetros cuadrados.

A = (10 - 7) · 10

A = 3 · 10

A = 30

El área de la franja amarilla del rectángulo es igual a 30 centímetros cuadrados.

Answer:

we are going to use the formula...
V=πr2h

Step-by-step explanation:

so

V = (3.14) 4x4 (9)

V = (3.14) 16 x 9

V = 3.14 x 144

V = 452.16

Hence, the third or C
