Answer:
v = 2034.72 mm³
Step-by-step explanation:
radius = 18mm
height = 6mm
pi = 3.14
v = πr²h/3
v = 3.14 * (18mm)² x 6mm/3
v = 3.14 * 324mm² x 2mm
v = 2034.72 mm³
Answer:
144 ft^2
Step-by-step explanation:
Back (vertical): (4 ft)(8 ft) = 32 ft^2
Right side (vert.): (4 ft)(6 ft) = 24 ft^2
Front (vert.): (4 ft)(10 ft) = 40 ft^2
Top (horizontal): A = (1/2)(6 ft)(8 ft) = 48 ft^2 total (top and bottom)
Total surface area is (32 + 24 + 40 + 48) ft^2, or 144 ft^2
Answer:
x = 
Step-by-step explanation:
AC² = AB² + BC²
BC² = 3² + x² = 9 + x²
AB² = 7² + x² = 49 + x²
But AC² = (7 + 3)² = 100
∴ 100 = 49 + x² + 9 + x²
2x² + 58 = 100
x² = 50 - 29 = 21
x =
The answers are 9.8 and 10/3
X = adult tickets
y= child tickets
x + y = 11
44.95x + 34.95y = 434.45
-44.95x - 44.95y = -494.45
-10y = -60
y = 6 child tickets
x + 6 = 11
x = 5 adult tickets
