Explanation:
Arithmetic Sequence Formula
a(n) = a1 + (a - 1) (d)
a= term position
a(n)= nth term
a1= first term
Answer:
9,424.8 cm^3
Step-by-step explanation:
V = A of circle x h
= πr^2 x h
=(3.1416)(10)^2 x 30
=(3.1416)(100) x 30
=314.16 x 30
=9429.8
<u>Solution</u><u> </u><u>:</u><u>-</u>
Here we can see that ∠b is vertically opposite to 68° angle and we know that vertically opposite angles are equal.
So , the measure of ∠ b will also be equal to 68° .
More to know :
- Alternate Interior angles are equal.
- Corresponding angles are equal.
- Sum of co - interior angles is 180° .
- Alternate exterior angles are equal.
- Measure of angle of straight line is 180°.
- Vertically opposite angles are equal.
