A spherical cabinet knob has a radius of 1.5 inches. Find the volume of thevcabinet knob.
1 answer:
Answer:
V=14.12 in³
Step-by-step explanation:
This is a tough one. To find the volume, you'll need the followimg equation:
The 3 next to the R is an exponent. An exponent involves multiplying the radius by itself. So it would look like this: 1.5×1.5×1.5
Next, you must multiply the result by 3.14. So it would be 3.375×3.14. And finally, you must multiply that result by 4 and divide by 3. So 10.59×4 to get 42.36 then divide that by 3. 42.36 divided by 3 is 14.2. (Answer can vary from time to time and you may need to round up)

Answer:
first option
Step-by-step explanation:
Given
y = 2(x - 3)² + 1
Rearrange making x the subject
Subtract 1 from both sides
y - 1 = 2(x - 3)² ( divide both sides by 2 )
= (x - 3)² ( take the square root of both sides )
± = x - 3 ( add 3 to both sides )
± + 3 = x
Change y into terms of x with x being the inverse, that is
(x) = ±
+ 3
