Answer:
Surface Area = 165.06 inches 2
Step-by-step explanation:
5.1 in.
3 in.
8.3 in.
Surface Area = 2×(5.1×3 + 5.1×8.3 + 3×8.3)
= 165.06 inches 2
V (cone) = (1÷3) × (r×r×h) л cm3
3 cone = 1 cylinder (if "h" and "r" is same)
There is two cone...
1st one: (1÷3) × 3×3×5 л cm3 = 15л cm3
2nd one: (1÷3) × 3×3×8 л cm3 = 24л cm3
15 + 24 = 39л cm3
<u>Answer:</u>
If the circumference of a circle is changed from 9 cm to 3 cm, then the diameter decreases by a factor of 3.
<u>Solution:</u>
Given, the circumference of a circle is changed from 9 cm to 3 cm,
We have to find how will the diameter change from the given equations?
We know that, diameter = 2 radius and circumference = 2π radius.
Hence, the diameter decreases by a factor of 3.
