1st step is to find the radius, then substitute into the formula for area of a circle

to find the radius, just halve the diameter
Answer:
The answer to your question is Volume = 12735.06 cm³
Step-by-step explanation:
Data
a = 11.26 cm
s = 13 cm
h = 29 cm
Formula
V = BH
Process
1.- Calculate the area of the base
Area = B = Pa/2
P = Perimeter
P = 6(13)
P = 78 cm
Area = (78)(11.26)/2
= 878.28/2
= 439.14 cm²
2.- Calculate the volume
Volume = BH
= (439.14)(29)
= 12735.06 cm³
Answer:

n ≈ 3
Step-by-step explanation:
9n-2<7+20

Addition and multiplication are commutative property so that mean no.
In this case, you have to do division.
Your answer is 6x = 72
x = 12
Hope this helps :)
