Probability =
(number or amount of possible successes)(total number or amount of possible outcomes)

Area of any circle is (pi) x (radius squared)

Area of the whole board = (pi) x (13 squared) = 169 pi square inches

Area of the shaded region = (pi) x (5 squared) = 25 pi square inches

Probability = (success area) / (total possible area) = 25pi/169pi = <u>0.15 </u>(rounded)

Notice that if you do it my way ... keep 'pi' in the fraction ... you don't even
need to know what the value of 'pi' is, because there's one in the top and
bottom of the fraction, and they cancel.

The volume of a sphere is 32 3 π cubic centimeters. What is the radius? Sphere V = 4 3 πr3
allsm [11]

Answer:

To solve for the volume of a sphere, you must first know the equation for the volume of a sphere.

V=43(π)(r3)

In this equation, r is equal to the radius. We can plug the given radius from the question into the equation for r.

V=43(π)(123)

Now we simply solve for V.

V=43(π)(1728)

V=(π)(2304)=2304π

Answer is 2304

Slope = 2/5; passes through (-3,1)
nydimaria [60]
Presumably we're after the line with that slope through that point.  In general the line through (a,b) with slope m is 

y-b = m(x-a)

Here we have a=-3, b=1, m=\frac 2 5

y - 1 = \frac 2 5 (x--3)

y = \frac 2 5 x + \frac 6 5 + 1

y = \frac 2 5 x + \frac{11}{5}

Check: The slope is clearly  \frac 2 5
 so we check

y = \frac 2 5 (-3) +\frac{11}{5} = \frac 5 5 = 1 \quad\checkmark
