A water tank has the shape of an inverted cone (like an ice cream cone without ice cream). the tank is 10m high and has a radius

Nostrana [21]

we know that

the surface area of the top of the water is calculated with the formula of the area of a circle

$A=\pi r^{2}$

Step 1

Find the radius of the water tank in the middle of the tank

by proportion

$\frac{10}{3} =\frac{5}{x} \\ \\ 10*x=5*3\\ \\ x=\frac{15}{10} \\ \\ x=1.5m$

so

For h=5 m

the radius is equal to r=1.5 m

Step 2

Find the surface area

$A=\pi*1.5^{2}$

$A=7.07\ m^{2}$

therefore

the answer is

the surface area of the top of the water is $7.07\ m^{2}$

Chantelle runs with sandals on. Chris runs with a long stride. Kevin runs with his hands at his chest. Sarah runs with the short

8_murik_8 [283]

Out of all of them I would say CHRIS bc your supposed to run in comfortable shoes for your feet's sake ( so that's a no to Chantelle). You are supposed to run with your arms swinging beside you or however just not still like kevin bc that burns energy you may need to finish the run. You are supposed to lengthen your stride, taking short strides for 1 burns energy and 2 it takes longer. hope this helps.
