Basically find the area of the bigger and smaller circle

a = pi * r^2

a = 3.14 * 7^2
a = 3.14 * 49
a = 153.86

a = 3.14 * 11^2
a = 3.14 * 121
a = 379.94

subtract the smaller area from the larger area:

379.94 - 153.86 = 226.08 sq cm

Answer:

Step-by-step explanation:

Non-shaded region area:

A= 3.14 x 7^2=153.86 cm²

The whole circle area:

A=3.14 x 11^2= 379.94 cm²

Area for ONLY the shaded region:

A= 379.94 - 153.86= 226.08 cm²

Find the components of the vertical force Bold Upper Fequalsleft angle 0 comma negative 8 right anglein the directions parallel

nydimaria [60]

Answer with Step-by-step explanation:

We are given that

F=<0,-8>=0i-8j=-8j

$\theta=\frac{\pi}{3}$

The component of force is divided into two direction

1.Along the plane

2.Perpendicular to the plane

1.The vector parallel to the plane will be= $r=cos\frac{\pi}{3}i-sin\frac{\pi}{3}j=\frac{1}{2}i-\frac{\sqrt 3}{2}j$

By using $cos\frac{\pi}{3}=\frac{1}{2},sin\frac{\pi}{3}=\frac{\sqrt 3}{2}$

Force along the plane will be= $\mid F_x\mid=F\cdot r$

Force along the plane will be = $\mid F_x\mid=F\cdot (\frac{1}{2}i-\frac{\sqrt 3}{2}j)=-8j\cdot(\frac{1}{2}i-\frac{\sqrt 3}{2}j)=8\times \frac{\sqrt 3}{2}=4\sqrt 3$ N
