Answer:
6) 9216π
8) 24
Step-by-step explanation:
6)
V= 2/3πr³
r = 48/2 = 24
V = 2/3π24³
V = 9216π
8)
V = 4/3πr³
2304π = 4/3πr³
r³= (2304π)/4/3π
r³= 1728
r = 12
D = 2r
D = 2 x 12 = 24
Answer:
Step-by-step explanation:
7) The tangent angles are 90° each.
The angles of a quadrilateral add up to 360°, so ? = 360°-90°-90°-73° = 107°.
8) Solve this the same way as question 7). ? = 360°-90°-90°-57° = 123°.
Questions 9) and 10) are cut off, so I assume you don't need to know those.
Answer:
Step-by-step explanation:
Distribute -2 through the parentheses
Similarly, Distribute 8 through the parentheses
Collect like terms
Move 2x to left hand side and change it's sign
Similarly, move 6 to right hand side and change it's sign
Collect like terms
Add the numbers : 16 and 6
Divide both sides by 2
Calculate
