Circumference = 2πr
So the circumference of the track is C = 2π .2 or .4π
3 times around the track is .4π x 3 or 1.2π - this is the answer but most teachers will want you to use 3.14 for pi.
so 1.2 x 3.14 = 3.768 km
Do you notice that I waited until the end to use the actual value of pi (3.14) in my calculations.
Keeping things in pi units until the very end saves time.
So 12x 8+96 and you do 12 time 8 because x=12 and then 2x2 because y+4 and times by 2 because there is a 2 in front and that equals 8 and then 8x2 because z is 2 and add both sides =112
answer
112
It is shifted 4 units DOWN. You can tell by the negative b value!

Answer:
(4500(Pi))/2 or 7068.585
Step-by-step explanation:
r = 15 cm
volume of a sphere:
(4/3)(Pi)r^3
Therefore:
(4/3)(Pi)15^3
15^3 = 3375
4/3 * 3375 = 4500
and since it is half a sphere (it is a bowl) the answer would be divided by two:
4500(Pi) divided by 2
14137.17 divided by 2
