41°F equals how many degrees Celsius?
GrogVix [38]
<span>So we wan't to know hot to convert degrees Fahrenheit to degrees Celsius. Let's transform first from Celsius to Fahrenheit: 0 degrees Celsius is 32 degrees Fahrenhiet and 1.8 degrees Celsius is 1 degree Fahrenheit so: T(F)=1.8T(C) + 32. To transform from Celsius to Fahrenheit we need to invert the former equation: 1.8T(C)= T(F)-32. Now we divide the whole equation with 1.8 and we get: T(C)=(T(F) - 32)/1.8 and input our T(F)=41 F and we get: T(C) =(41-32)/1.8 and that is equal to: T(C)= 5 C. So the correct answer is B. 5 degrees C</span>

A cone has a volume of 24 cubic inches. What is the volume of a cylinder that the cone fits exactly inside of?
Soloha48 [4]

Answer:

72 cubic inches

Step-by-step explanation:

Volume of cone = \frac{1}{3}\pi r^{2} h   --1

Volume of cylinder = \pi r^{2} h  --2

We are given that a cylinder should fit exactly inside the cone

On comparing 1 and 2 we can see:

\text{Volume of cone}= \frac{1}{3} \text{Volume of cylinder}

Since we are given the volume of cone is 24 cubic inches .

So, 24= \frac{1}{3} \text{Volume of cylinder}

24 \times 3= \text{Volume of cylinder}

72= \text{Volume of cylinder}

Hence the volume of cylinder is 72 cubic inches

Option D is correct.
