Find the circumference of a circle with a diameter of 15 inches... Round to the nearest tenth and include units in your answer..

rosijanka [135]

Answer:

47. 1 inches ; where inches ⇒ units

Step-by-step explanation:

Consider the Circumference as such;

$Diameter - 15 inches,\\Circumference - 2\pi r, r - radius,\\\\2\pi r = \pi d, d - diameter ( considering, 2 * r = diameter )\\\\Circumference = \pi * d = \pi * diameter = \pi * 15 = ( About ) 47.1 inches\\Solution; Circumference = ( About ) 47.1 inches$

From this we can tell that ⇒ Answer; 47. 1 inches, where inches - units

At the Roberts family reunion, there are 48 men. The ratio of men to women is 6.5. How many women are at the reunion

ruslelena [56]

Your answer would be approximately 30 women because:
40/6=6.6 (repeating)
since there cant be .6 of a woman, we will get rid of .6
now we have 40/6=6
finally:
6*5= 30

i hope this helps you! :)

In the xy-plane, the graph of x2 − 4x + y2 − 6y = −8 is a circle. What is the radius of the circle?

Blizzard [7]

The center-radius form of the circle equation

$(x-h)^2+(y-k)^2=r^2$

(h, k) - center

r - radius

We have:

$x^2-4x+y^2-6y=-8$

Use

$(a-b)^2=a^2-2ab+b^2\qquad(*)$

$x^2-2(x)(2)+y^2-2(y)(3)=-8\qquad\text{add}\ 2^2\ \text{and}\ 3^2\ \text{to both sides}\\\\\underbrace{x^2-2(x)(2)+2^2}_{(*)}+\underbrace{y^2-2(y)(3)+3^2}_{(*)}=2^2+3^2-8\\\\(x-2)^2+(y-3)^2=4+9-8\\\\(x-2)^2+(y-3)^2=5\\\\(x-2)^2+(y-3)^2=(\sqrt5)^2\\\\Answer:\\\\\boxed{center:(2,\ 3)}\\\\\boxed{radius:r=\sqrt5}$
