Answer:
the formula represent the correct way is π(4)^2 (5)
Step-by-step explanation:
The formula that represent the correct way to calculate is given below:
As we know that
Volume = πr^2 h
where
r denotes the radius i.e. 4 inches
And, h denotes the height i.e. 5 inches
Now placed these values to the above formula
So,
= π(4)^2 × 5
= 80π in^3
Hence, the formula represent the correct way is π(4)^2 (5)
Answer:
$872
Step-by-step explanation:
Simple interest = Principle * Rate * Time / 100
= ( 800 * 6 * 18/12 ) / 100
= $ 72
The balance after 18 months = principle + interest
= 800 + 72
= $ 872
Answer:
x=6
Step-by-step explanation:
We can write this as a ratio
x 9
---- = --------
10 15
Using cross products
15x = 10*9
15x = 90
Divide by 15
15x/15 = 90/15
x =6
Answer:
Sometimes
Step-by-step explanation:
An acute angle is an angle that measures less than 90°
So, an angle that is less than 180° is sometimes acute.
