Question 1156537


if one side of triangle is 148 feet long and the altitude to that side is 56 feet long, the area of triangle is

{{{A=(1/2)148*56}}}

{{{A=74*56}}}

{{{A=4144}}}square feet

if there is a circular water fountain that has a concrete base that has a radius of {{{10}}} feet, the area of water fountain is

{{{A[1]=r^2*pi}}}

{{{A[1]=10^2*pi}}}

{{{A[1]=100*3.14}}}

{{{A[1]=314}}}

the area of the lawn to be fertilized is 

{{{A-A[1]=4144-314}}}

{{{A-A[1]=3830}}}

How many bags of fertilizer that covers {{{10}}} square feet will be enough to fertilize the lawn?

{{{3830/10=383}}}

so, {{{383}}}  bags of fertilizer will be enough to fertilize the lawn
