A bricklayer uses a cylinder to store sand. The cylinder is 5 ft tall and has a radius of 0.5 ft. Each batch of mortar contains 0.48 ft3 of sand.
How many batches of mortar can the bricklayer make with 1 cylinder of sand?
Use 3.14 to approximate pi, andround your final answer to the nearest whole number.

i will medal
OpenStudy (welshfella):
first find the volume of the cylinder
this = 3.14*r^2*h where r = radius and h = height
OpenStudy (anonymous):
ok so what would be V=3.14r^2H

then to find the number of batches of mortar divide this volume by 0.48
OpenStudy (anonymous):
ok
OpenStudy (welshfella):
V = 3.14 * 0.5^2 * 5 ft3
OpenStudy (anonymous):
3.925 FT3
OpenStudy (welshfella):
right

so wut now
OpenStudy (welshfella):
so no. of batches = 3.925 / 0.48
OpenStudy (anonymous):
8.177083333

??? ><__><
OpenStudy (welshfella):
right again
- round this to nearest whole numb er = ?
