A right circular cylinder has a height of 19 3/4 ft and a diameter 1 2\5 times its height.

alexira [117]

Answer:

Volume of cylinder is 34833.21 ft³

Step-by-step explanation:

Given : A right circular cylinder having height $19\frac{3}{4}$ ft and diameter $\frac{12}{5}$ times its height.

Given : diameter $\frac{12}{5}$ times its height that is

diameter $\frac{12}{5}$ times $19\frac{3}{4}$ that is

Diameter = $\frac{12}{5} \times \frac{79}{4}$

Diameter = $\frac{237}{5}$ ft

Radius is half of diameter,

Radius = $\frac{1}{2} \times \frac{237}{5}=\frac{237}{10}$ ft

$\text{Volume of Cylinder}=\pi r^2h$

Substitute the values, we get,

$\text{Volume of Cylinder}= \pi (\frac{237}{10})^2 \times \frac{79}{4}$

$\text{Volume of Cylinder}= \times 3.14 \times (23.7)^2 \times 19.75$

$\text{Volume of Cylinder}=34833.21$

Thus, volume of cylinder is 34833.21 ft³

La mamá del profesor Ernesto tiene una bolsa con 3/4 kilogramos de arroz y guiso 2/3 de su contenido Que fracción de un kilogram

VARVARA [1.3K]

Answer: ella usó (1/2) kg de arroz para cocinar.

Step-by-step explanation:

La madre de Ernesto tenía una bolsa con 3/4 kg de arroz.

Sabemos que uso 2/3 de esa cantidad para hacer un guiso.

Entonces ella usó 2/3 de 3/4 kilogramos de arroz.

Entonces ella usó:

(2/3)*(3/4) kg de arroz.

Recordemos que esto se puede escribir como el producto entre los numeradores dividido por el producto de los denominadores:

(2*3)/(3*4) kg de arroz.

(6/12) kg de arroz

(1/2) kg de arroz.

Esto significa que ella usó (1/2) kg de arroz para cocinar.
