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:
x + 5(-x - 2)= 2
x - 5x - 10 = 2
-6x - 10 = 2
-6x = 12
x = -2
y = 2 - 2 = 0
(-2, 0)
answer is no
Answer:
n=3p
Isolate the variable by dividing each side by factors that don't contain the variable.
Pi=3.14, So 86 x 3.14= [ 270.04]
Answer:
proof is below
Step-by-step explanation:
Answer:
25^9 + 5^17=
=2^18 + 5^17
=5^17(5+1)
=5^17×6
=5^16×30 is divisible by 30
