Question

Hena stores coffee powder in a steel container with a capacity of 82.5 cubic inches. He uses a glass container to store sugar. The two containers are congruent cylinders. If the glass container has a height of 4.2 inches, what is its radius?

Answer 1

volume of a cylinder = Base Area x Height
Base Area= area of circle
\[V = \pi r^2 h\]
congruent will mean they have equal volume

let V = 82.5 and let h = 4.2

\[82.5= \pi \times 4.2 \times r^2\]

Answer 2

SO whats the answer? :\

Answer 3

82.5/π/4.2=6.25 squared =2.5
