192.5=1/2(26+12.5)h. What is the unknown measure

Answers

Answer 1

Answer:

$\bf \textit{area of a trapezoid}\n\n A=\cfrac{h(a+b)}{2}~~ \begin{cases} a,b=\stackrel{bases}{parallel~sides}\n h=height\n[-0.5em] \hrulefill\n a=12.5\n b=26\n A=192.5 \end{cases}\implies 192.5=\cfrac{h(12.5+26)}{2} \n\n\n 385=h(12.5+26)\implies 385=38.5h\implies \cfrac{385}{38.5}=h\implies 10=h$

The diameter of a cylinder is 3yd the height is 8yd

Answers

Answer:

volume= 56.55 yds

Step-by-step explanation:

If you're looking for the volume, the formula is $V=\pi r^(2) h$ .

Diameter is two times the radius (radius is half of the diameter) so the radius of the cylinder would be 1.5 yds.

After you've gotten that information, plug those values into the formula.

$V=\pi 1.5^(2) 8$

Solve 1.5^2 first. Then multiply that value by pi. Then multiply that value by the height which is 8yds.

Volume=56.55yds rounded to the nearest hunderedth.
