Answer:

Diámetro = 8 metros

Step-by-step explanation:

La ecuación de la circunferencia esta en la forma general y para identificar su centro y su radio debemos llevarla a la forma canónica completando cuadrados:

x^{2} +y^{2} -28y + 180= 0

Solo necesitamos completar cuadrados en la variable y, sumando a ambos lados de la ecuación 196, que resulta de dividir 28 entre 2 y elevarlo al cuadrado

x^{2} +y^{2} -28y + 196 = -180 +196

Entonces obtenemos

x^{2} + (y-16)^{2} = 16

E identificamos que el radio del tanque es 4 metros y por tanto su perímetro es 8 metros

den301095 [7]

Answer:

1cm, 2.4cm, 2.6cm

Step-by-step explanation:

They have to follow the pythagorean theorem a^2+b^2=c^2.

1^2+2.4^2=2.6^2 so it follows the pythagorean theorem so these three squares would form a right triangle.

Answer:

2 1/4 gallons

Step-by-step explanation:

If 3/4 covers 1/3 of the wall, you need to multiply 3/4 by 3, which gives you 9/4, or 2 1/4 gallons

In the triangle below, determine the value of a.
makkiz [27]

Answer:

Step-by-step explanation:

This is classic right triangle trig.  Side a, our unknown, is adjacent to angle C which is a given.  You always have to use a given angle and side to find a missing side, so we have to figure out how the two givens are related to our unknown.  Side a is adjacent to angle C, and we are also given the hypotenuse.  We know side a is not the hypotenuse since the hypotenuse is ALWAYS the side across from the 90 degree angle.  The tan ratio of angle C will give us a way to have only one unknown.

tan 43 = a/26 and

26 tan 43 = a

Use your calculator now to find the missing side.  

a = 24.2 units long
