Answer:
your answer should be 4095
The formula for the volume of a cone is V= πr² (h/3).
V= 3.14 (12²) (8/3)
V= 3.14 (144) (2.6...)
V= 1205.76
V≈ 1206
So the answer is A.
Answer: so i got 31 but if you round it it will be 30 hope it helps
Step-by-step explanation:
Answer:
Radius of the cone is 6 unit.
Step-by-step explanation:
Given:
Lateral Surface Area of Cone, LSA = 100π unit²
Total Surface Area of cone, TSA = 136π unit²
Let, r be the radius of cone.
According to the question,
Total Surface area = lateral surface area + Area of circle
136π = 100π + πr²
πr² = 36π
r² = 36
r = 6
Therefore, Radius of the cone is 6 unit.
Answer:
21
Step-by-step explanation:
1/5 of 30 is 6
10% of 30 is 3
3+6=9
30-9=21
which is 7/10
