Answer:

Altitude of cylinder = 10 cm

Step-by-step explanation:

Given:

lateral surface area of cylinder = 90 cm²

Circumference of base = 9 cm

Find:

Altitude of cylinder

Computation:

Circumference of base = Circumference of cylinder

So,

2πr = 9

lateral surface area of cylinder = 2πrh

2πrh = 90

We know that; 2πr = 9

So,

9(h) = 90

h = 90 / 9

Altitude of cylinder = 10 cm

Find the value of the missing coefficient in the factored form of 27f^3 + 125g^3. 27f^3+125g^3=(3f+5g)(9f^2-?fg + 25g)^2

7nadin3 [17]

Answer:

Step-by-step explanation:

The formula for factoring a sum of cubes is:

$a^3+b^3=(a+b)(a^2-ab+b^2)$

We have a=3f and b=5g here.

So a*b in this case is 3f*5g=15fg.

The ? is 15.
