X/y = 4 , x = 4y
x^2 -12y^2 = (4y)^2 - 12y^2 = 16y^2 -12y^2 = 4y^2
Answer:
The volume of the cylinder B is greater than that of cylinder A
Step-by-step explanation:
To know which cylinder has the greater volume, we need to find the volumes of both cylinders.
The volume of a cylinder is given as:
CYLINDER A
Radius, r = 3 m
Height, h = 1.2 m
Volume, V, will be:
The volume is
CYLINDER B
Radius, r = 4 m
Height, h = 2.5 m
Volume, V, will be:
The volume is
The volume of the cylinder B is greater than that of cylinder A.
So, here in part a), we are given n terms (no specific no. of terms given), so no. of terms = n , also, the common difference is defined as the difference between the next term to a specific term and the term, i.e , where d is the common difference, so here d = 49 - 45 = 4
Also, here the last term is 49 let say it the nth term, as no number of terms are given, so using the Arithmetic Progression formula, we can write as ;
Now, as we assumed there are n terms, so using the sum formula, we can have ;
Now, for part b) we are given a geometric progression with first term = a = 1, common ratio = r = (3/1) = 3, and no. of terms = n = 6, so now putting all values in the sum formula we will have;
