Answer:
20π or 62.8
Step-by-step explanation:
Volume of a cone = 1/3πr²h
1/3(π)(2)²9
= 12π or 37.7
Volume of a hemisphere = 2πr²/3
2(π)(2)²
= 8π or 25.1
Total Volume = 20π or 62.8
Answer:
A: (3^2)*2
B: (2^3)*3
C: 2*19
D: (3^2)*9
Step-by-step explanation:
We have:
A) 18= 3*3*2= (3^2)*2
B) 24=2*2*2*3=(2^3)*3
C) 38 = 2*19
D) 81 =3*3*9=(3^2)*9
The answer is 566m because 147 plus 147 and 136 plus 136 equals 566
