= 5 × 7 - 5×4√3 + 2√3 ×7 - 2√3 × 4√3
= 35 -20√3+ 14√3-8×3
= 35 - 6√3 -24
= 11-6√3
Answer:
36 times larger.
Step-by-step explanation:
V= is the original volume of a cone formula.
If the radius is multiplied by 6 the new formula is:
V=
Which is simplified to:
V=
The only difference between the simplified formula and the original is the *36 so the new volume is 36 times larger when the radius is multiplied by 6.
