A hard candy has a radius of 9 mm. The candy has a spherical soft center with a radius of 6 mm, with a hard shell surrounding it
goblinko [34]
Well you have to subtract the soft shell volume from the entire candy volume. Using the formula for the volume of a sphere, the whole candy is 4/3*729*3.14=3052.08
the soft center is 4/3*216*3.14= 904.32. If you subtract, you get the answer of 2147.76 mm^3.

Please help, Brainliest if correct!!!

See the attached pic below

In the triangle formed by the statue and the boat, we have

\tan23^\circ=\dfrac x{110+y}

and

\tan38^\circ50'=\dfrac xy

We can solve either equation for y, then substitute that into the other equation. First, let's abbreviate t_1=\tan23^\circ and t_2=\tan38^\circ50'. Then

y=\dfrac x{t_2}

\implies t_1=\dfrac x{110+\frac x{t_2}}

\implies\dfrac{t_1}{t_2}=\dfrac x{110t_2+x}

\implies(110t_2+x)\dfrac{t_1}{t_2}=x

\implies110t_1=\left(1-\dfrac{t_1}{t_2}\right)x

\implies x=\dfrac{110t_1}{1-\frac{t_1}{t_2}}=\dfrac{110t_1t_2}{t_2-t_1}

\implies\boxed{x\approx99}
