Answer:
B
Step-by-step explanation:
Substitute the following values into the cylindrical volume equation below:
r= 30/2 = 15 cm
h = 320 cm
V=πr2h
V=(3.14)(15)^2 (320)
V=226 080 cm^3
if the question is (x + 5)^2, the product is x^2 + 10x + 25.
The answer is D! 4(2a + 3) = 8a + 12
The required equation is:

Step-by-step explanation:
Given
Let a be Anne's Age
and
b be Betty's age
Now we will onvert the given word problem in the form of equation step by step
"twice Betty's age." will be represented by 
Then
"3 years younger than twice Betty's age." will be represented as: 
Now
"Betty's sister, Anne, is 3 years younger than twice Betty's age."

Hence,
The required equation is:
