If r is the radius of a sphere its surface area = 4(pi)r^2.
If the radius is doubled then its surface area = 4(pi)(2r)^2 = 4*4(pi)r^2.
So the surface area becomes 4-fold or the increase in surface area is 300%.
Answer:
Angle 1 = 105
Angle 2 = 75
Step-by-step explanation:
Angle 2 and angle 75 are corresponding angles.
Corresponding angles are equal.
So,
Angle 2 = 75
Angle 1 and angle 2 are linear pair angles.
Angle 1 + Angle 2 = 180
Angle 1 + 75 = 180
Angle 1 = 180 - 75
Angle 1 = 105
If you would like to know how many pints should Jake measure, you can calculate this using the following step:
1 pint ... 2 cups
x pints = ? ... 8 cups
1 * 8 = 2 * x
8 = 2 * x /2
x = 8/2 = 4 pints
The correct result would be 4 pints.
Answer: 16 inches
Step-by-step explanation:
Complete question
(A cylindrical container can hold about 1256 cubic inches of water. the diameter of the cylinder is 10 inches long. approximate the height if the cylinder to the nearest inch . Use 3.14 to approximate the value of pi)
Volume of a cylinder = 3.14 * r² * h
r = radius of the cylinder
H = height of the cylinder
Pi = 3.142
Radius = diameter/ 2
R = 10/2 = 5 inches
1256 = 3.14 * 5² * h
1256 = 78.5h
Divide both sides by 78.5 to get h,
H = 1256 / 78.5 = 16 inches
The height of the cylinder is 16 inches
