What is the radius of a hemisphere with a volume of 165\text{ cm}^3,165 cm 3 , to the nearest tenth of a centimeter?
DanielleElmas [232]

Answer:

4.3cm

Step-by-step explanation:

the radius of the hemisphere can be determined its volume

volume of a hemisphere = (2/3) x (n) x (r^3)

n = 22/7

r = radius

(2/3) x (22/7) x( r^3) = 165 cm^3

44/21 x r^3 = 165

divide both sides of the equation by 21/44

165 x 21/44

r^3 = 78.75

find the cube root

r = 4.2863 cm

the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

the 100th terms, 8 is greater than 6, so add 1 to 2. this give 4.3cm

The slope of a line is 2. The y-intercept of the line is –6. Which statements accurately describe how to graph the function?
Butoxors [25]

Answer:

The correct answer is the first one of your list of options:

"<em>Locate the ordered pair (0, –6). From that point on the graph, move up 2, right 1 to locate the next ordered pair on the line. Draw a line through the two points</em>."

Step-by-step explanation:

Since the y-intercept is -6, then the point (0, -6) is a point on the line.That is x = 0 and y = -6. From there you move according to the slope value "2 = 2/1" which means two units of rise when the run is one.

Then, from (0, -6) move up 2 units and then right one unit. The new point should also be a point on the line. Join the two points with a line to graph the function.
