I believe it might be B but I'd need to see the graph
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:
Explanation down below.
Step-by-step explanation:
10% of 91.25 = 9.125.
20% of 91.25 = 18.250.
30% of 91.25 = 27.375.
40% of 91.25 = 36.500.
36.500 × 2 = 73.
B, 70 dollars.
-5+-5=-10 so the sum is -10
