1. The cylindrical vase shown is filled with decorative stones. If 30% of the space inside the
cylinder is filled with air, find the volume of air
inside of the cylinder to the
nearest tenth.

7 cm. 10 cm.

A. 115.4 cm.3
B. 384.7 cm.3
C. 461.6 cm.3
D. 1,538.6 cm.3

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).

the answer is a if my teacher taught me correct

#12 the answer is the third option
