A cylinder has a volume of 288pi cubic meters and a height of 9 meters. what is the area of the base?​
Nikolay [14]

Answer:

100.54m²

Step-by-step explanation:

Given parameters:

Volume of the cylinder = 288pi cubic meters = 288πm³

Height of the cylinder = 9m

Unknown parameter:

Area of the base = ?

Solution

To find the unknown which is the base area of the cylinder, we simply use the formula of the volume of a cylinder.

Volume of a cylinder = Base area x height = πr² x h

where π is a constant

           r is the radius of the cylinder

           h is the height of the cylinder

     

From here, we make area the subject of the formula:

       Base area(πr²) = \frac{Volume of cylinder}{height of cylinder}

      Base area =  \frac{288 π}{9} = 32 π = 100.54m²

Find the length of the line segment that joins the points (2, 5) and (9, 8).
arsen [322]
Distance formula : sqrt ((x2 - x1)^2 + (y2 - y1)^2)
(2,5)...x1 = 2 and y1 = 5
(9,8)...x2 = 9 and y2 = 8
now we sub
d = sqrt ((9 - 2)^2 + (8 - 5)^2)
d = sqrt ((7^2) + (3^2))
d = sqrt (49 + 9)
d = sqrt 58 <===

What is the product of (3a 2)(4a2 â€"" 2a 9)? 12a3 âÂ’ 2a 18 12a3 6a 9 12a3 âÂ’ 6a2 23a 18 12a3 2a2 23a 18.
Kay [80]

The product of (3a + 2)(4a^2 - 2a + 9) will be  12a^3 + 2a^2 + 23a + 18.

Given expression,

(3a + 2)(4a^2 - 2a + 9).

We have to find the product of (3a + 2)(4a^2 - 2a + 9).

Now using distributive property, we get

3a(4a^2) - 3a(2a) + 3a(9) + 2(4a^2) - 2(2a) + 2(9)

12a^3 - 6a^2 + 27a + 8a^2 - 4a + 18

12a^3 + 2a^2 + 23a + 18

 

Hence the product of (3a + 2)(4a2 - 2a + 9)  is 12a^3 + 2a^2 + 23a + 18.

Thus the correct option is (D). 12a^3 + 2a^2 + 23a + 18.
