A revolving water sprinkler sprays water in all directions for a distance of 25ft .What area does it cover?Round to the nearest 10ftsquared.

490

Step-by-step explanation:

the equation is A = π x r^2

find the radius which is half of 25, 25 divided by 2= 12.5

multiply the radius by itself to square it so its going to be 156.25

multiply the results with pi

156.25 x 3.14= 490.625

round it to the nearest 10 is going to be 490

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
