Tcecarenko [31]

Answer:

0.318 Pa

Step-by-step explanation:

Area of a circle= πr²

Area= π x 10²

Area= 314 m²

Pressure = force/area

Pressure = 100/314

Pressure = 0.318 Pa

P.S. You can substitute Pascals for N/m²

Hope this helps!

Find the later area of the figure

o-na [289]

Answer:

$\large\boxed{60\pi\ sq.in.}$

Step-by-step explanation:

The formula of a lateral area of a cone:

$L.A.=\pi rl$

r - radius

l - lateral height

We have the radius r = 6in and the height H = 8in.

Use the Pythagorean theorem to calculate the lateral height:

$l^2=6^2+8^2\\\\l^2=36+64\\\\l^2=100\to l=\sqrt{100}\\\\l=10\ in$

Substitute:

$L.A.=\pi(6)(10)=80\pi\ in^2$
