Fraction=8/20 kids ate a grilled cheese at her restaurant in the last week. This simplifies to 2/5. Therefore the probability that a randomly selected child at her restaurant is eating a grilled cheese is 2/5.
Area of circle = pi r^, (r)radius is half the diameter so 9÷2=4.5 so in this scenario it would be 3.14×4.5^
3.14×4.5×4.5=63.6
circumference of circle= diameter×pi (3.14)
so 9×3.14=28.3
Answer:
Step-by-step explanation:
step 1
Find the area of the garden space
First convert mixed number to an improper fraction
step 2
Find how much more land Farmer Jack needs to plant the rest of his corn
We use direct proportionality:
360⁰......Pi×R² (full circle)
120⁰.......x
x=120×pi×R²/360=pi×R²/3
x=pi×4²/3=16.76mi²
A=3×pi cm², for an angle of 2×pi/3=120⁰
In a similar way we compute the area of the full circle:
360.........x
120..........3×pi
x=3×pi×360/120=9×pi=3²×pi.
Thus the radius is 3cm.
Answer:
The playground covers 
of a square mile
Step-by-step explanation:
The playground is a rectangular ground. The area of a rectangle is given by legth * width, hence,
The area of the playground is length * width
Area = 
sq. mi
Hence the playground cover of a square mile
