How to find the area of 2 half circles and a rectangle

gladu [14]

Hello!

We use different formulas to calculate the areas of different shape.

RECTANGLE:

To find the area of a rectangle, we must simply multiply its length by its width. The formula for its area is:

A = l × w

SEMICIRCLE:

Since the formula for a circle is pi × r × r, we must use the same formula but divide it in half, because a semicircle is a half circle, which is why its area would also be half of a circle's. The formula for a semicircle's area is:

A = 1/2 pi × r × r

Tip:

Write these formulas down and memorize them so that you don't forget them. You'll have to use these formulas quite often when finding the area of these shapes.

6- en la clase de repostería, inés y liz prepararon una torta de naranja. para ello, utiliza 1/2 litro de leche y 1/3 de jugo de

WITCHER [35]

Answer:

El total de líquido utilizado es $\frac{5}{6} de litro$ . Se echa $\frac{1}{6}$ de litro más de leche que de jugo

Step-by-step explanation:

Para saber la cantidad total de líquido, basta con sumar las cantidades de leche y de jugo de naranja. Vamos a asumir que usa 1/3 de litro de jugo de naranja.

En este caso el total de líquido es 1/2 litro + 1/3 litro. Dado que estas fracciones tienen distinta denominador, debemos sumarlas de la siguiente manera

$\frac{1}{2}+\frac{1}{3} = \frac{1\cdot 3 + 2\cdot 1}{2\cdot 3} = \frac{5}{6}$

Para calcular la cantidad extra de leche de más que la cantidad de jugo, restamos estos números. Es decir

$\frac{1}{2}-\frac{1}{3} = \frac{1\cdot 3 - 2\cdot 1 }{2\cdot 3} = \frac{1}{6}$

Es decir, que echamos $\frac{1}{6}$ de litro más de leche que de jugo.
