Answer:
Volume of the cylinder is. 1017.36
Step-by-step explanation:
is the area of a cylinder.
Let's plug in our values.
-----
3.14 = pi
9 = radius
x = height
-----
V = (3.14)(9)^2(4)
V = (3.14)(81)(4)
V = (3.14)(324)
V = 1017.36
Let's formulate an equation first. For exponential growth, we follow the formula. b = 800, r - 0.027. Hence,
y = 800(1+0.027)^t
Then, at t = 21, y will be determined
y = 800 (1+0.027)^21
y = 1399.81 = 1400
Thus, the amount of bacteria present after 21 hours is 1400.
Answer: An inequality
Step-by-step explanation:
An inequality is a mathematical sentence written with a greater than
sign, or less than sign, or equal to sign or not equal to sign or more than two of these signs at the same time to join two expressions.
the answer is 216.81 I looked it up on a calculator
