What is the volume of both shapes ?
Nataly [62]

Answer:

314 ft cubed

Step-by-step explanation:

To find the volume, find the volume of the cone and add it to the volume of the cylinder.

The volume of a cone is

V= \frac{1}{3}\pi r^2 h=  \frac{1}{3}\pi (5^2)(12) =  \frac{1}{3}\pi (25)(12)= \frac{1}{3}\pi *300 = 100\pi.

The volume of the cylinder is

V=\pi (5^2)(4)= \pi (25)(4)= 100\pi

Together their volume is 100\pi+100\pi=200\pi \\200\pi =314ft^3

Stacy bought a skateboard at a local sporting goods store. The skateboard was on sale for 10% off the original price. The store

The original price will be larger than the final price because you would be taxing the discounted price not the original price.

Yes. If you add the sales tax first then the discount wont be on just the product. it would be on the product and the tax with the product. so you have to first get the discounted price from the store and then tax for the county.

The speed that a tsunami can travel is modeled by the equation s = 356 startroot d endroot , where s is the speed in kilometers
Naddika [18.5K]

The approximate depth of water for a tsunami traveling at 200 kilometers per hour is 0.32 km.

<h3>What is speed?</h3>

Speed can be calculated as the ratio of distance traveled to the time taken.

The speed that a tsunami can travel is modeled by the equation

s = 356√d, where s is the speed in kilometers per hour and d is the average depth of the water in kilometers.

S = 356√d

200 = 356√d

√d = 200/356

= 0.5618

d = 0.5618^2

= 0.316 km

d = 0.32 km.

Thus, The approximate depth of water for a tsunami traveling at 200 kilometers per hour is 0.32 km.
