Answer:
0.077
Step-by-step explanation:
Marco can divide 77 by 1000 to convert it to dekagrams
There are 0.077 decagrams per 77 centagrams

The given points are (1,1),(1,3) and (9,2)
equation of circle is
8x²+8y²+ax+by=0
let us plug in (1,1) in the equation we get
8+8+a+b=0
a+b=-16
let us now plug in (1,3) in the equation
8+8*3²+a+3b=0
a+3b=-80
let us. now solve the two equation in terms of a and b
we get
2b=--64
b=-32
and
a=-16+32
=16
therefore the equation is
8x²+8y²+16x-32y=0
Hope this helps
Assuming you're just computing the volume, i.e.

we should convert to cylindrical coordinates first, setting

so that the volume is given by

which has a value of

.
Easily, take the square root of the number in the right side to find the radius

is the answer
5 out of 12 = 5/12
Those are
1 - 106
2 - 137
4 - 120
6 - 195 and
8 - 139
