Square roots the square root of 1 is one square root of 2 is 4 square root of 3 is 9 and ect.
Answer:
1. 32 inches = 81.28 centimeters
2.402 000 millimeters = 402 meters
3. 2.85 meters = 285 centimeters
4.2 kilometers= 2000000 millimeters
5. 71 meters = 0.071 kilometers
6. 8kg = 8000 g
7. 3000 g = 3 kg
8. 2.5 kg = 2500 g
9 850 mg = 9.85 g
10.75 dg = 1075 m
Answer: Length = 12cm , width = 21cm
Step-by-step explanation:
Let the length be x , then the width is x + 9, That is
Length = x
Width = x + 9
The formula for calculating the perimeter of a rectangle is given by:
Perimeter = 2 ( Length + Width )
substituting the values , we have :
66 = 2 ( x + x + 9 )
66 = 2 ( 2x + 9 )
divide through by 2
66/2 = 2x + 9
33 = 2x + 9
subtract 9 from both sides
33 - 9 = 2x
24 = 2x
divide through by 2
therefore :
x = 12
This means that
Length = 12cm
Width = 12 + 9 = 21 cm
Answer:
83.333333π
Step-by-step explanation:
the volume of a cone is (1/3) · π · r^2 · h, so 1/3 times pi times 5^2 times 10
which is 83.3pi, or 261.7
