If the circle below is cut from the square of plywood below, how many square inches of plywood would be left over? Use π = 3.14,
1 answer:
Answer:
86in²
Step-by-step explanation:
Find the complete question attached
Area of the circle = πr²
Area of the square = L²
Length of the side of the square
r is the radius of the circle
r = L/2 = 20/2 =10in
Given
Length of the side of the circle = 20in
Area of the square = 20²
Area of the square = 400in²
Area of the circle =π(10)²
Area of the circle = 3.14(100)
Area of the circle= 314in²
Amount of plywood left over = 400in²-314in² = 86in²

Scientific notation is
where 1≤x<10 and b is an integer
b is how many spaces you had to move the decimal to the left in the original number to obtain x
so
48,100,000,000,000
to
4.8100000000000
the decimal was moved 13 spaces
so b=13
a=4.81
