To get the tax, you would have to multiply the $262 by 105%. since a percent is just 1/100 you can do 262•1.05. This would equal 275.1.
Your answer is $275.10
Area of circle: A=pi×r². This area coresponds to 360degrees, or 2×pi radians.
2×pi ....... pi×r²
t radians....x
where t=2.75rads
Area of t: x=pi×r²×t/2/pi=r²×t/2
Area of t: 3²×2.75/2=9×2.75/2=12.375
Answer: the area of 2.75 radians is 12.375
The volume of the larger ball bearing is 8 times the volume of the
smaller one
Step-by-step explanation:
All the spheres are similar, and there is a ratio between their radii
So the ratio between their:
1. Diameters⇒ =
2. Areas ⇒ =
3. Volumes ⇒ =
∵ The radius of the larger ball bearing is twice the radius of the
smaller one
- That means the radius of the larger sphere is equal to the radius
of the smaller sphere multiplied by 2
∴ =
∵ =
∴ =
∴ =
<em>The volume of the larger ball bearing is 8 times the volume of the </em>
<em>smaller one</em>
