Answer:C) 36:1

Step-by-step explanation:

The formula for determining the volume of a cylinder is expressed as πr^2h

Where

h represents the height of the cylinder.

r represents the radius of the cylinder.

π is a constant.

These two right circular cylinders have the same height, 45 centimeters.

The radius of the smaller cylinder is 22 centimeters and the radius of the larger cylinder is 6 times greater than that of the smaller cylinder. This means that the radius of the larger cylinder would be

6 × 22 = 132 centimeters

Volume of the larger cylinder would be

π × 132^2 × 45 = π × 17424 × 45

Volume of the smaller cylinder would be

π × 484× 45

the ratio of the volume of the larger cylinder to the volume of the smaller cylinder would be

(π × 17424 × 45) / (π × 484× 45)

= 36 : 1

Does anyone know how to do these maths question???

Answer:

Part 1) $f(g(x))=3(x^2)+2$

Part 2) $g(f(5))=289$

Step-by-step explanation:

we know that

A composite function is a function that depends on another function. A composite function is created when one function is substituted into another function

we have

$f(x)=3x+2$

$g(x)=x^{2}$

Part 1) Determine f(g(x))

To find f(g(x)) substitute the function g(x) as the variable in function f(x)

$f(g(x))=3(x^2)+2$

Part 2) Determine g(f(x))

To find g(f(x)) substitute the function f(x) as the variable in function g(x)

$g(f(x))=(3x+2)^2$

For x=5

$g(f(5))=(3(5)+2)^2$

$g(f(5))=289$

How can the answer me 9x9x8x7 if you are not supposed to repeat digits?

user100 [1]

Answer: 4,536

Step-by-step explanation: Multiply your two 9's to get 81. Multiply your 8 and 7 to get 56. Multiply 81 and 56 together to get your answer of 4,536.

9 x 9 = 81

8 x 7 = 56

81 x 56 = 4,536

Use long multiplication to evaluate this equation.

I hope this helps you out! ♥

Brums [2.3K]

Answer:

729

Step-by-step explanation:

$\frac{1}{2}log_{2}x=3log_{2}3 \\$

$log_{2}\sqrt{x} =log_{2}3^{3}$

$\sqrt{x} =27 \\$

x=27²=729

"Ten subtracted from the quotient of a number<br> and 5 is 18."

Anika [276]

Answer: n/5 - 10 = 18: this would be the equation. Your answer would be 140.

Step-by-step explanation: Let consider the number as ‘X’

Quotient of a number and 5 can be written as

X divided by 5

Ten subtracted from the quotient of a number and 5 can be written as

(X divided by 5)-10

Ten subtracted from the quotient of a number and 5 is 18 can be written as

(X divided by 5)-10=18

By solving the above equation, find ‘X’

(X divided by 5) = 18 + 10

X/5=28

X = 28 x 5 = 140
