Mathematics

Answer:

Height is 8.0in

Step-by-step explanation:

Surface Area of a cylinder = 2πr(r+h)

r is the radius

h is the height of the cylinder

Given surface area = 408.41in²

radius = 5in

h = ?

Substituting the given value into the formula

408.41 = 2π(5)(5+h)

408.41 = 50π + 10πh

408.41 = 50(3.14)+10(3.14)h

408.41 = 157+31.4h

408.41-157 = 31.4h

251.41 = 31.4h

h = 251.41/31.4

h = 8.0in

Aleksandr-060686 [28]

Answer:

  22.81

Step-by-step explanation:

The distance formula can be used to find the distances between pairs of vertices. The perimeter is the sum of those distances.

<h3>Side lengths</h3>

The distance formula is ...

  d = √((x2 -x1)^2 +(y2 -y1)^2)

Using this formula the triangle side lengths are ...

  AB = √((6 -(-2))^2 +(2 -2)^2) = √(8^2) = 8

  BC = √((0 -6)^2 +(8 -2)^2) = √(6^2 +6^2) = 6√2

  CA = √((-2 -0)^2 +(2 -8)^2) = √(4 +36) = √40

The perimeter of the triangle is the sum of these lengths:

  P = 8 +6√2 +2√10 ≈ 22.8098

The perimeter is about 22.81 units.

El piso de un habitación es de forma cuadrada. Tiene 10m de longitud por lado y debe ser cubierto con losetas cuadradas de 25cm
lora16 [44]

Answer:

4 fichas

Step-by-step explanation:

Paso 1

Encontramos el área de la habitación cuadrada.

Área de un cuadrado = longitud del lado²

Longitud lateral = 10 cm

Área del piso cuadrado = (10cm) ²

= 100 cm²

Paso 2

El suelo debe estar cubierto con baldosas cuadradas de 25 cm.

Por lo tanto: El número de mosaicos que serán necesarios =

Área del piso cuadrado ÷ Área de las baldosas

= 100cm² / 25 cuadrados

= 4 fichas
