That is not difficult.
The area of the garden is S=A-B
A is the area of the square: A=25 x 25=625
B is the area of the house: B= 20x15= 300
So we have S=625-300=325
With the known ratio, we can calculate the cost: 55*S= 55*325= 17,875
We have to pay Rs 17,875
Have fun

The volume of 2 spheres have a ratio of 27:125. what is the ratio of their radii

Citrus2011 [14]

The volume is scale factor³
Take the square root of the volume ratio

$\sqrt{ \frac{27}{125} }$ which is
$\frac{ \sqrt{27} }{ \sqrt{125} }$

$\frac{3}{5}$

The ratio of their radii is 3 : 5

Find the total surface area of the rectangular prism in square millimeters. 2cm 6 cm 9cm

Ket [755]

<h3>Answer: 168 square cm</h3>

==============================================

Work Shown:

L = 2 = length
W = 6 = width
H = 9 = height

The order of length, width and height doesn't matter

SA = surface area of rectangular prism

SA = 2*(LW + LH + WH)

SA = 2*(2*6 + 2*9 + 6*9)

SA = 2*(12 + 18 + 54)

SA = 2*(30+54)

SA = 2*(84)

SA = 168 square cm

The volume of a cylinder is given by the formula v= m'h. where r is the radius of the cylinder and h is the height.

Verdich [7]

Answer:

The Volume of cylinder is: $\mathbf{Volume=2\pi x^3-5\pi x^2-24\pi x+63\pi }$

Option B is correct option.

Step-by-step explanation:

We are given:

Volume of cylinder = h = 2x+7

Radius of cylinder = r = x-3

We need to find volume of cylinder

The formula used is: $Volume=\pi r^2h$

Putting values and finding volume

$Volume=\pi r^2h\\Volume=\pi (x-3)^2(2x+7)\\Volume=\pi (x^2-6x+9)(2x+7)\\Volume=\pi (2x(x^2-6x+9)+7(x^2-6x+9))\\Volume=\pi (2x^3-12x^2+18x+7x^2-42x+63)\\Volume=\pi (2x^3-12x^2+7x^2-42x+18x+63)\\Volume=\pi (2x^3-5x^2-24x+63)\\Volume=2\pi x^3-5\pi x^2-24\pi x+63\pi \\$

So, The Volume of cylinder is: $\mathbf{Volume=2\pi x^3-5\pi x^2-24\pi x+63\pi }$

Option B is correct option.
