Answer:
48in²
Step-by-step explanation:
to find the area of a triangle you first divide the base by 2 then multiply it by the height
Percent relative error is calculated by the formula: (experimental value - literature value/ experimental value) x 100%
Therefore, (6-7/7) x 100% = 14.3%
Your answer is in absolute value :)
Answer:
5127079.21 cubic feet
Step-by-step explanation:
The silo is in the shape of a cylinder and a cone.
The volume of the silo will be the sum of the volumes of the cylinder and the cone.
Therefore, its volume is:

where r = radius of cylinder and cone
h = height of cylinder
H = height of cone
The radius of the base is 120 feet, the height of the roof (cone) is 25 feet. The height of the entire silo is 130 feet. This means that the height of the cylinder is:
130 - 25 = 105 feet
Therefore, the volume of the silo is:

The volume of the silo is 5127079.21 cubic feet.
Answer:
m∠J = m∠Z = 46°
Step-by-step explanation:
m∠J = m∠Z = 46°
The probability that will not rain today is: 85%
100% - 15% = 85%
The correct answer is A
