Step-by-step explanation:
first work out wax used for cone using formula
1/3 x 3.14 x r squared x height
using this the total for the candle must be 113
formula for a sphere is 4/3 x 3.14 x r cubed
so we know 113 /3.14 / 4/3 = r cubed
cube root 27 = 3

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 3x² - 7x
f(-2) is x = -2
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(-2) = 3(-2)² - 7(-2)
- Exponents: f(-2) = 3(4) - 7(-2)
- Multiply: f(-2) = 12 + 14
- Add: f(-2) = 26
