the sides of a square field are 12 meters. A sprinkler in the center of the field sprays a circular area with a diameter that corresponds to a side of the field. How much of the field is not reached by the sprinkler? round your answers to the nearest hundredth
Answers
Answer 1
Answer:
diameter=side
find area of field (square) and area of sprinkler (circle)
ara of square=side^2 area of circle=pir^2
area of square=12^2=144
area of circle=pir^2 d/2=r 12/2=6=r area=pi6^2 area=36pi aprox pi=3.14 area=113.04
area wasted=area of field-arrea of sprinlker area wasted=144-113.04=30.96 m^2
in 10 min calebs heart can beat 700 times .Steve's heart beats 536 times in 8 minutes how many more times does calebs heart beat in 5 minutes than Steve's heart
Answers
Assuming that their heart will not increase speed or decrease speed of beating Caleb: 700 times/ 10 minutes = 70 times/minute, hence in 5 minutes his heart beats 70 * 5 = 350 times Steve: 536 times/ 8 minutes = 67 times/minute, hence in 5 minutes his heart beats 67 * 5 = 335 times 350-335 = 15 times Caleb's heart beat 15 times more than Steve's in 5 minutes

Ricky is filling an 8 inch by 4 1/2 inch rectangular box with packing peanuts. The peanuts are cubes that come in two different sizes ,1 cubic inch and 1/8 inch .How many peanuts of each size are needed to fill the box?
Answers
Ok, so we can fill the part of the box that corresponds to the 8x4 inches with the boxes that are 1 cubic inch - that wound be 8x4, that is 32 such boxes.
then the rest would be 8x inches, that is 4 cubic inches.
In order to fill in 4 cubic inches with inches boxes we calculate:
So it's also 32 such small boxes!
