the diameter of a cylinder is 7 yd. the height is 8 yd. find the volume and use pi and round to nearest 10th. V=__yd 3 little th
hichkok12 [17]

We can find the volume of the cylinder using the next equation:

V=\pi r^2h

Where h represents the height and r represents the radius.

The radius is the half value of the cylinder. Then :

r=d/2

r=7yd

r=3.5yd

Replacing:

\begin{gathered} V=\pi(3.5yd)^2(8yd) \\ V=98\pi yd^3 \end{gathered}

Hence, the volume is 98π yd³

98π yd³=307.9

The answer is decimal form is 307.9 ( The value is rounded to the nearest tenth).

The coordinates of A are (1/4,3). The coordinates of B are (1/2,4.5). If the x-coordinate of C is 7/4, what is its y-coordinate
vagabundo [1.1K]

Answer:

10.5

Step-by-step explanation:

Given

A = (1/4, 3)

B = (1/2, 4.5)

To get the coordinate of C as 7/4, what was done was to first take the difference in the x coordinates and then dilate the result by 7

To get the y coordinate;

  • Take the difference in the coordinate

Difference = 3 - 4.5

Difference = -1.5

  • Dilate the result by factor of 7

This is done y multiplying the result by 7;

y coordinate = 1.5 * 7

y coordinate = 10.5

Hence its y-coordinate is 10.5
