Try this option:
1. the required surface area consists of: A=A₁+A₂+A₃, where
2. A₁=pi*r*l - the surface of the cone:
pi=3.14; r=4/2=2 cm; l=sqrt(6²+2²)=2√10≈6.33 (cm);
A₁=3.14*2*6.33=39.74 (cm²).
3. A₂=a²-pi*r² - the surface of the top plane:
A₂=36-3.14*4=23.43 (cm²).
4. A₃=5*a² - the surface of the five planes of the given cube:
A₃=5*6²=180 (cm²).
5. the required area:
A=39.74+23.43+180=243.17 (cm²).

<u>Answer: 243.17</u>
Answer:
Step-by-step explanation:
Given
Required
The volume of the sphere
This is calculated as:
So, we have:
This gives:
I think 55 because you would multiply 11×5
Answer:
3/10, 30%
Step-by-step explanation:
the shaded region is 9/30 which is equivilent to 3/10 and 3/10is 30 percent.
hope this helps!
