You and a friend want to know how much rope you need to climb a large rock.  your friend is 5.5 feet tall and casts a shadow that is 18 feet long.  if the rock casts a shadow that is 209.5 feet long, calculate the height of the rock from the ground.  round your answer to the nearest foot.   (hint: make a drawing)

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
