You can double the product of 9 and 4 to get to the product of 9 and 8
Answer:
r = 2.39 and C=2πr=2·π·2.39≈14.99997
Step-by-step explanation:
Using the formula
C=2πr
Solving for r=C 2π=15
2·π≈2.38732
and then u round up the 7 told the 8 to go up.
2.39
<span>Given the two end of the diameter of the circle, we are able to compute the center of the circle as 0.5*[(-1,3)+(7,-7)]=(3,-2). The radius of the circle is 0.5*sqrt[(-1-7)^2+(3+7)^2]=sqrt(41). Therefore the equation of the circle is (x-3)^2+(y+2)^2=41.</span>
Answer:
3888pi cm^3 or 12214.5122372 cm^3
Step-by-step explanation:
To being, let's list out what we know
The volume of a sphere is
V = 4/3(pir^3)
But this is only half of a sphere, so the volume of it should be
V =2/3(pir^3)
With the diameter of the shape being
d = 36
We will first need to find the radius to use the formula above
r = d / 2
= 36 / 2
= 18
Now, let's start plugging in values
V = 2/3(pi18^3)
= 2/3 ( 5832pi)
= 3888pi or 12214.5122372
