This is the concept of volume of solid materials, we are required to find the diameter of cone with height 8 and volume 150 m^3.
volume of cone is given by;V=1/3 (pi*r^2*h)
making r^2 the subject we get;
V/(pi*h)=r^2
inserting the values in our formula we get:
150/(pi*8)=r^2
r^2=5.97
thus;
r=sqrt(5.97)=2.44
But ;
diameter=2*radius
thus
diameter=2.44*2
=4.88 m
Answer:
a) 7/10
b) There is no improper fraction form for this
Answer: 412.38
Step-by-step explanation: 0.79 x 522
111% increase
Equation:
3.49x = 3.89
x = 11%
2 1/6
multiply the fraction to see the answer. if you multiply 4 and 1 third by three sixth you get 2 3/18 which is the same as 2 1/6.
