Answer: 21.21 meters

Step-by-step explanation:

Hi, to answer this, first we have to calculate the circumference (C) of the wheel:

C = π x diameter

Replacing with the values given:

C = π x 45 = 141.37 cm

Then we multiply it by the number of revolutions:

141.37 x 15 = 2,120.6 cm

Since  

1 cm = 0.01 m

2,120.6 x 0.01 = 21.21 meters

Feel free to ask for more if needed or if you did not understand something.

hammer [34]

Answer:

To find the result of 300 - 650, we can:

a) do 650 + 300 and keep the result sign

b) do 650 + 300 and invert the result sign

c) do 650 - 300 and keep the result sign

d ) perform 650 - 300 and invert the result sign

Step-by-step explanation:

The correct answer is the letter D .

(perform 650 - 300 and invert the result sign)

300 - 650

300 is more than - 650 on the number line this is because of the negative sign of 650

so we can also write it as 650 - 300 and after getting the require result with put the negative sign to the result, so the result will be -350

Keep the sign of the number with the highest absolute value and subtract from it the lowest absolute value.

- (650 - 300)

Subtract the numbers.

- 350

therefore, the answer is d ) perform 650 - 300 and invert the result sign

<h3>Area of a Square Pyramid</h3>

The formula of a square pyramid is given as

A = l^2 + 2l\sqrt{\frac{l^2}{4} + h^2} \\

Let's substitute the values and solve for the area of the square pyramid.

A = l^2 + 2l\sqrt{\frac{l^2}{4} + h^2} \\\\A = 3^2 + 2*3\sqrt{\frac{3^2}{4} + 3.63^2} \\A = 9 + 6{\sqrt{15.43} } \\A = 32.57ft^2

Since the cost of 1 square foot  = Rs. 560

32.57 ft^2 = x

1sq = 560\\32.57 = x\\x = 32.57 * 560\\x = 18,239.2

The cost of 32.57ft^2 is Rs. 18,239.2 which is the cost of renting one tent.
