Answer:
A
Step-by-step explanation:
it’s gonna have to add up to 180°, and 5 x 8 - 6 = 34
89 + 57 = 146
146 + 34 = 180
PT=ST and QT=TR, when angles are verticals their opposite arcs are equivalent. i think. someone feel free to correct me if this is wrong
The volume of a cone is V= (1/3)pi r²h
it was given
h=12cm
radius=3cm
the volume of the first cone is V1= 1/3)pi r²h1
where h1= h/2=6cm
so its volume is V1=1/3)xpix3²x6=56.52cm^3
and since the two cones are identical so V1=V2=<span>56.52cm^3,
we need </span><span>56.52cm^3 or salt </span>
