Answer:
They use 741 dollars
Step-by-step explanation:
Write 65% as
65/100
Since, finding the fraction of a number is same as multiplying the fraction with the number, we have
65/100 of 1140 = 65/100× 1140
Therefore, the answer is 741
If you are using a calculator, simply enter 65÷100×1140 which will give you 741 as the answer.
A number 1/10 as great as 7962 would be 796.2
You get this answer by either dividing 7,962 with 10 which gives you 769.2
Or you can multiply 7,962 with 1/10 to get 7,962/10. If you simplify then you get 796 1/5 or 796.2.
The perimeter of a circle is its total circumference, but in this case a semi-circle will measure half the circumference plus its diameter.
If the semicircle measures 8cm then the total circle is 16 cm, and we can calculate its diameter or radius from there. The perimeter is defined as:
p = pi*diameter = 16
diameter = 16/pi = 16/3.14
diameter = 5.1 cm
Therefore the semi-circle perimeter is:
perimeter = semi-circle + diameter = 8 + 5.1 = 13.1 cm
If the height and radius of a cylinder are doubled, the volume of the cylinder will also double or will be higher. This is true because the formula for calculating cylinder’s volume is: V=πr2h; where r is the radius while h is the height. However, as you can see on the formula the radius has more effect than height.
