Answer:
Step-by-step explanation:
Angle c = 90 degrees
90 + 2x + x = 180 degrees
3x = 90
x =30 degrees
2x = 30*2 = 60 degrees
Answer:
(a+b+c) (x+y+z)

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:
v=-60
Step-by-step explanation:
In the circumference formula given d is the diameter which is 2 times r ( r is the radius)
R is given as 6 feet, diameter = 2 x 6 = 12 feet.
Circumference = 12 feet x 3.14 = 37.68 feet
