Answer:
635.2 cm^3.
Step-by-step explanation:
Volume of the cylinder = π r^2 h
= 3.14 * 4^2 * 5 = 251.2
Volume of the prism = 4 *8 * 12
= 384
Total volume = 384 + 251.2
Answer:
x = 7
Step-by-step explanation:
7x + 1 = 130 = 180
7x = 180 - 130 - 1
7x = 49
x = 7

Answer:
The answer is 12.
Step-by-step explanation:
The question says QS is a tangent to circle P which means to QS is perpendicular 90° to QS. With provided information, we are able to find the value of QS using Pythogoras' Theorem, a²+b² = c² :
Let c = PR+RS = 5+8 = 13 units,
Let b = PQ = 5 units,
Let a = QS,
13² = 5² + QS²
QS² = 13² - 5²
= 169 - 25
= 144
QS = √144
= 12 units
