We have that
<span>Cylinder A has a radius of 2 feet and a height of 4 feet
so
volume of the cylinder A=pi*r</span>²*h-----> pi*2²*4-----> 16*pi ft³
<span>Cylinder B also has a height of 4 feet, but the radius has been doubled
</span>h=4 ft
r=2*2---> 4 ft
so
volume of the cylinder B=pi*r²*h-----> pi*4²*4-----> 64*pi ft³
volume cylinder B/volume cylinder A=64*pi/(16*pi)----> 4
therefore
the answer is the option
<span>C) When the radius is doubled, the resulting volume is 4 times the original volume.</span>
Answer:
Option C
Step-by-step explanation:
Given that area of a circle = 452.16 sq metres
Hence radius = ![\sqrt{\frac{452.16}{3.1416} } =11.9969 m](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B452.16%7D%7B3.1416%7D%20%7D%20%3D11.9969%20m)
After rounding off we get radius = 12metres
To find circumference
We know that circumference of a circle = 2pir
= ![2(3.1416)(11.99694)=75.3984 m](https://tex.z-dn.net/?f=2%283.1416%29%2811.99694%29%3D75.3984%20m)
Option C is right
Option D is right
hint; the sum of all angles in a triangle is 180° !
^so all together it’s gonna be 180 !
hope this helped !
i’m pretty sure the value of it (x) is 12 but am not sure
Answer:
3.2
Step-by-step explanation:
to solve this equation, you need to first separate the coefficient 5.5 from x. To do this, you must divide BOTH sides. 5.5x ÷ 5.5 = 17.6 ÷ 5.5
x= 3.2
