A cone with a radius of 6 cm has a volume of 1200 cm3. What is the height of the cone? (The volume of a cone is given by the for

Rina8888 [55]

Answer:

31.8 cm

Step-by-step explanation:

Volume of a cone:

V = 1/3πr²h

We have:

V = 1200 cm³
r = 6 cm
h = ?

Substitute values and solve for h:

1200 = 1/3*3.14*6²h
1200 = 37.68h
h = 1200/37.68
h = 31.8 cm (rounded)

Answer:

47.13 for 17 melons

Step-by-step explanation:

We can use a ratio to solve

24.95 x dollars

---------------- = ----------------

9 melons 17 melons

Using cross products

24.95 * 17 = 9x

Divide by 9

24.95 * 17/9 = x

47.127777777 = x

Rounding to the nearest cent

. Part A: Under a dilation of scale factor 3 centered at the origin, AB becomes A'B'. Determine the coordinates of A'B' and sket

Ne4ueva [31]

Answer:

Step-by-step explanation:

Part A.

Coordinates of A and B are,

A(-2, 2) and B(3, 2)

Rule for dilation of a point (x, y) by a scale factor k about the origin,

(x, y) → (kx, ky)

If the points A and B are dilated by a scale factor 3, image points will be,

A(-2, 2) → A'(-6, 6)

B(3, 2) → B'(9, 6)

Part B.

Following the same rule of dilation about the origin by a scale factor of $\frac{1}{2}$ about the origin,

A(-2, 2) → D(-1, 1)

B(3, 2) → $C(\frac{3}{2},1)$
