I’m pretty sure they all are real numbers-
The quarter circle pieces are all congruent allowing us to glue them together to form a circle. The circle will be completely inside the square. This circle is as large as possible so it's not spilling outside of the square.
The area of the square is 8*8 = 64 square units
The circle has a radius of 8/2 = 4 units. Use r = 4 and plug this into the area of a circle formula
A = pi*r^2
A = pi*4^2
A = pi*16
A = 16pi
Now subtract the two areas
(area of square) - (area of circle) = 64 - 16pi
The exact answer, in terms of pi, is 64 - 16pi
If your teacher wants you to find the approximate decimal version, then you would use a calculator to find that 64 - 16pi = 13.7345175 approximately. If you end up going with the approximate answer, be sure to follow the instructions on what your teacher wants with rounding.
Answer:
35.4÷ 0.59=60
Step-by-step explanation:
Answer:
Step-by-step explanation:
The largest factor that will divide evenly into both 32 and 48 is 16.
Thus, 32 - 48 = 16(2 - 3), or 16 (-1), or just -16.
Are you sure there wasn't more to this problem?
The average speed of Joshua during that time is 2500 m/h.
Explanation:
It is given that Joshua started cycling at 5:15 pm. By 8:09 pm he has covered a distance of 7250 m.
The total time taken by Joshua from 5:15 pm to 8:09 pm is
Dividing we get,
Adding, we have,
Thus, the total time taken by Joshua is 
To determine the average speed we use the formula,
where 
and 
Hence, substituting the values we have,
Dividing, we get,
Thus, the average speed of Joshua during that time is 2500 m/h.
