Circle A would make more sense (I'm not exactly sure) because it shows the entire circle (if you know what I mean).
Alex Ar [27]3 years ago
6 0
Area A = 10^2(<span>π/180x90 - sin90)
Area A = 28.54

</span>Area B = 12^2(π/180x60 - sin60)
Area B = 13.04

segments <span>CED </span>has a greater area

so answer
Circle A: radius = 10m, m∠CAD = 90°

(03.05 LC) The graph of a function f(x) is shown below: graph of line segment going through ordered pairs negative 3, negative 4
Aleks [24]

Answer:

−3 < x ≤ 1

Step-by-step explanation:

The domain of a function is the set of x-values.

In this graph, the open circle at (-3, -4) means the segment goes back up to this point but this point is not part of the segment itself.

The closed circle at (1, 2) means this is the endpoint and part of the segment.

This means the x-values range from almost -3 up to and including 1; this gives us the inequality

−3 < x ≤ 1

Calculate the mean of the number set 5 10 12 4 6 11 13 5
son4ous [18]
For calculating the mean, you want to add up all of the numbers then divide by how many numbers there are. So you'd do:

5+10+12+4+6+11+13+5 then divide that by 8

The answer to your question is: 8.25

The amount Lin's sister earns at her part-time job is proportional to the number
gulaghasi [49]

Answer:

y = 9.6x

Yes, y is a function of x.

x =  \frac{5}{48} y

Step-by-step explanation:

For a proportional relation, the equation is given by:

y = kx

where k is the unit rate of change.

We were told that, Lin's sister earns $9.6 per hour.

This means k=9.6.

We substitute to get:

y = 9.6x

We could rewrite this as

y(x) = 9.6x

Yes, y is a function of x.

To obtain an equation describing x as a function of y, we solve for x to get:

x =  \frac{1}{9.6} y

Find the volume of the cone of with a height of 6cm and a diameter of the base or 6cm
Ainat [17]

Answer:

The volume of cone v= 113.04 cm³.

Step-by-step explanation:

Formula used to find volume of cone is:

v= \pi * r^2 * \frac{h}{3}

where r is the radius and h is the height of cone.

In the given question we are given:

height h= 6 cm

diameter d= 6 cm

We know radius r = d/2 = 6/2 = 3 cm

so, volume will be:

v= \pi * 6^2 * \frac{3}{3}

v= \pi * 36

v=113.04

So, the volume of cone v= 113.04 cm³ given height h= 6cm and radius r= 3cm
