A cylinder has a base diameter of 14m and a height of 10m. What is its volume in cubic m, to the nearest tenths place?
VARVARA [1.3K]

Answer:

1539 cubic meters

Step-by-step explanation:

Hello, I can help you with this

to solve need  we will need these two equations

Step one

Remember

area of a circle

Area=\pi *\frac{diameter^{2} }{4}\\

Also, the volume of the cylinder

Volume= area of the circle * height

Volume=\pi *\frac{diameter^{2} }{4} *height\\

Step 2

put the values into the equation

Let

diameter= 14 m

height = 10 m

Volume=\pi *\frac{diameter^{2} }{4} *height\\\\Volume=\pi *\frac{(14\ m)^{2} }{4} *10\ m \\\\Volume=\pi *49\ m^{2} *10\ m\\Volume=1539.38\ cubic\ meters

I hope it helps,have a great day.

For which of the following decreasing functions f does (f−1)′(10)=−1/8
Oduvanchick [21]

Recall the inverse function theorem: if f(x) has an inverse, and if f(a) = b and a = f⁻¹(b), then

f⁻¹(f(x)) = x   ⇒   (f⁻¹)'(f(x)) • f'(x) = 1   ⇒   (f⁻¹)'(f(x)) = 1/f'(x)

⇒   (f⁻¹)'(b) = 1/f'(a)

Let b = 10. Then pick the function f(x) such that f(a) = 10 and f'(a) = -8 for some number a.

Use a division ladder to find the GCF of 34 and 60. A4 B3 C1 D2
Sloan [31]

Answer:

D.2


Step-by-step explanation:

First, you need to divide 34 and 60 by A.4, when you divide that you see that 4 dose not go in to 34 evenly and go"s in to 60 evenly, so this is incorect.


Now we will divide 34 and 60 by B.3, when you divide, you see that 3 dose not go into 34 evenly and go"s in to 60 evenly, so this is also incorect.


Then we divide 34 and 60 by C.1, when we divide this one you find that 1 go"s in to 34 evenly and 60 evenly, so this is a posible answer.


finally we divide 34 and 60 by D.2, when we do this we find that 2 go"s in to 34 evenly and 60 evenly, so this is also a posible answer.


All though C. and D. both go in to 34 evenly and 60 evenly, we are looking for the GCF (Greatest Common Factor). So the biggest number of C.1 and D.2, is D.2


So the answer is D.2.


Hoped this helped, Have a grate day!
