Determine the radius of the cone, if the volume of the cone is 125cm and the height of the cone is 12cm. Round your answer to th
e nearest hundedth.
1 answer:
Answer:
3.15cm
Step-by-step explanation:
1. Determine where the given numbers go in formula for the volume of the cone.
2. Multiply ⅓ and 12cm to get 4
3. Isolate the section with unknown variables by dividing 125 and 4 to get 31.25 (rounded)
4. Now isolate the r² by dividing π by 31.25 to get 9.95
5. Take the square root of r and 9.95 to get rid of the exponent.
6. The radius is the answer of square rooting 9.95
7. If asked to check your answer, fill in the formula for the volume of the cone with the radius and round the answer to see if you get the volume you were originally given.
Hope this helps! :)

J'(-2,5)
K'(-7,5)
M'(-3.5,2)
L'(5.5,2)
Step-by-step explanation:
Please refer to the image attached to this answer.
Trapezoid JKLM is reflected over the x-axis, what do we notice about the ordered pairs of the original figure and the ordered pairs of its reflection over the x-axis is described below.
Point J , K L and M , when reflected over x axis , there distance from the y axis remains the same in second quadrant. the x coordinate becomes negative however the y coordinates remains the same.
The coordinates will be as shown in the image attached.
