Find the area of a circle with a diameter of 6. Either enter an exact answer in terms of pi or use 3.14 for pi
ankoles [38]
So it gives you the diameter but you need the radius of the circle to find the area so to find the radius you just divide the diameter by two. the formula for the area of a circle is A=pi*r^2 so you just multiply 3.14 by 3 squared so you just put it in the calculator as A=3.14*3^2 and you get 28.26 hope this helped

What is the solution to the equation?
Oxana [17]

ANSWER

(C) d=1

EXPLANATION

The given equation is

\frac{ - 3d}{ {d}^{2} - 2d - 8} +  \frac{3}{d - 4}  =  \frac{ - 2}{d + 2}

Factor the first fraction to get,

\frac{ - 3d}{(d + 2)(d - 4)} +  \frac{3}{d - 4}  =  \frac{ - 2}{d + 2}

Multiply through by (d+2)(d-4)

- 3d + 3(d + 2) =  - 2(d - 4)

Expand:

- 3d + 3d + 6 =  - 2d + 8

6 =  - 2d + 8

6  - 8=  - 2d

- 2 =  - 2d

divide both sides by -2

d = 1

A rectangular mat has a length of 12 in. and a width of 4 in. Drawn on the mat are three circles. Each circle has a radius of 2
AVprozaik [17]
Area of the rectangular mat = 12 x 4 = 48 in²

Area of the 3 circles = 3( πr²) = 3(3.14 x 2²) = 37.68 in²

P(landing in a circle) = 37.68/48 = 157/200 = 0.79 (nearest hundredth)

Answer: The probability of landing in one of the circles is 0.79.
