Answer:2034.7
Step-by-step explanation:
The equation is pi •r^2•h
R=6
H=18
Sum of n terms = a1 (r^n-1/ (r-1)
Sum of first one = 3 * (4^5 - 1) / 3 = 1023
.. 2nd = 5 * (6^2 - 1) / 5 = 35
.. 3rd = 5 ^4 - 1 / 4 = 156
.. 4th = 4 * (5^4 - 1) / 4 = 624
So in increasing order its 2nd, 3rd, 4th and first.
Answer:

Step-by-step explanation:
From the picture attached,
Multiplication of two fractions gives the result as
.
This shows that the denominator of the fractions when multiplied with each other results a number that will be the multiple of 10.
Therefore, from the given numbers,
5 × 6 = 30
Rest two numbers be placed as the numerator of the fractions.


Therefore,
will be the answer.
The image of the diagram is missing, so i have attached it.
Answer:
a = 30°
Step-by-step explanation:
From the diagram attached, we can see that the 2 angles a and 5a are interior supplementary angles.
The sum of interior supplementary angles is 180°
Thus;
5a + a = 180
6a = 180
a = 180/6
a = 30°
