Answer:
1. 30 metres
2. 27 squared feet,
3. 25.13 cm
4. 50.27 sqared inches
5. 15.71 metres
6. 380.13 squared metres
7. Area is: 4.52 squared metres Circumference is: 7.54 metres
8. Circumference is: 47.12 feet Area is: 176.71 squared feet
Step-by-step explanation:
1. Since you're rounding pi, your calculation would be:
2 × 3 × 5 = 30
---------------------------------------------------------------------------------------------------------------
2. Since you're rounding pi, it would be:
3 × 3² = 27
---------------------------------------------------------------------------------------------------------------
3. Use the formula for number 5
---------------------------------------------------------------------------------------------------------------
4. Use the formula in number 6
---------------------------------------------------------------------------------------------------------------
5. Formula for the circumference of a circle is:
[tex]C=2\pi r[/tex]
So:
2 × 3.14 × 2.5 = 15.71
---------------------------------------------------------------------------------------------------------------
6. Formula for the area of a circle is:
[tex]A=\pi r^2[/tex]
So:
3.14 × 121 = 380.13
---------------------------------------------------------------------------------------------------------------
7. Use the formula for numbers 5 and 6 to figure these out
---------------------------------------------------------------------------------------------------------------
8. Use the formula for 5 and 6, except divide the diameter by 2 because the formula only works with the radius
---------------------------------------------------------------------------------------------------------------
Have a good day :)
