Si el lado de un cuadrado mide 10cm cuanto mide él área del círculo que se encuentra adentro de ese cuadrado

Alex17521 [72]

Answer:

El área del círculo que se encuentra en el cuadrado es de 78.5cm²

Step-by-step explanation:

Para resolver este ejercicio tenemos que pensar que un cuadrado tiene sus 4 lados iguales, por lo que todos sus lados medirán 10cm.

Ahora nos fijamos que necesitamos saber para calcular el área de un circulo

a = área

r = radio

π = 3.14

a = π * r²

como podemos ver no sabemos el valor del radio

como el circulo toca con los 4 lados del cuadrado sabemos que su radio sera la distancia del centro del cuadrado a cualquiera de los lados.

Entonces tenemos que dividir un lado por 2

10cm/2 = 5cm

El radio del circulo sera 5cm

Ahora que tenemos todos los datos podemos calcular el valor del área

a = 3.14 * (5cm)²

a = 3.14 * 25cm²

a = 78.5cm²

El área del círculo que se encuentra en el cuadrado es de 78.5cm²

suppose the distnace in feet that an object travels t seconds is given by the formula d=64t^2 how far would the object travel af

Darya [45]

Answer:

The object travels 144,000,000 feet.

Step-by-step explanation:

The distance the object travel after t seconds is given by:

$d(t) = 64t^2$

How far would the object travel after 1.5 * 10^3 seconds

This is d when $t = 1.5 \times 10^3 = 1500$ , so $d(1500)$

$d(1500) = 64*1500^2 = 144000000$

The object travels 144,000,000 feet.

Mrs. Stevens is wanting to buy new border for her math bulletin board in the hallway l. The length of the board is 6.9 meters. T

kiruha [24]

Answer:

The quantity of board which Mr. Stevens need to buy is 22.4 meters

Step-by-step explanation:

Given as :

The length of board = 6.9 meters

The width of board = 4.3 meters

Let The measure of new board = x meter

Now,

The measure of new board = The perimeter of board

∵ The board is of rectangle figure

As, The perimeter of rectangular board = 2 × Length + 2 × width

So, The measure of new board = 2 × Length + 2 × width

or, x = 2 × 6.9 + 2 × 4.3

or, x = 13.8 + 8.6

or, x = 22.4 meters

So, The measure of new board = x = 22.4 meters

Hence The quantity of board which Mr. Stevens need to buy is 22.4 meters Answer
