Answer:
18.852:50.272
Step-by-step explanation:
Step one:
given
The radii of two right circular cylinders are in the ratio 3 : 4
r1= 3
r2= 4
Their heights are in the ratio 1 : 2
h1= 1
h2= 2
Step two:
The expression for the curve surface area is
CSA= 2πrh
CAS1= 2πr1h1
CAS1= 2*3.142*3*1
CAS1= 18.852
CAS2= 2πr2h2
CAS2= 2*3.142*4*2
CAS1= 50.272
The ratio of their curved surface areas
=18.852:50.272
The answer is 7 3/4.
Turn into improper fraction
= 77/8 − 15/8
= ((77 × 8) − (15 × 8)) / (8 × 8)
= (616 - 120) / 64
= 496/64
= 31/4

The solution of an equation is the true value of the equation.
The true statement is <em>(a) Dr. Ellison is right</em>
<em />
The equation is given as:
The solution is given as: (1,18)
Substitute 1 for x and 18 for y.
So, we have:
Multiply
Add
The above equation is true.
Hence, the true statement is (a) Dr. Ellison is right
