Answer:

Connect the intersections of the diameters and the circle with a segment

Step-by-step explanation:

Assuming the construction creates two orthogonal diameters, their ends will be the vertices of the inscribed square. Connecting them with segments in order around the circle will create the square.

The radius of a cylinder is 5 cm and the height is 7 cm.

nadezda [96]

Answer:

V = πr²h

V = 3.14 (5cm)²(7 cm)

V = 3.14 (25cm²) ( 7 cm)

V = 3.14 (175 cm³)

V = 549.50 cm³

A triangular plot of land has one side along a straight road measuring 147147 feet. A second side makes a 2323degrees° angle wit

Answer:

81.23 ft and 77.88 ft long

Step-by-step explanation:

The sum of the internal angles of a triangle is 180 degrees, the missing angle is:

$a+b+c=180\\a+23+22=180\\a=135^o$

According to the Law of Sines:

$\frac{A}{sin(a)}= \frac{B}{sin(b)}= \frac{C}{sin(c)}$

Let A be the side that is 147 feet long, the length of the other two sides are:

$\frac{A}{sin(a)}= \frac{B}{sin(b)}\\B=\frac{sin(23)*147}{sin(135)}\\B=81.23\ ft\\\\\frac{A}{sin(a)}= \frac{C}{sin(c)}\\C=\frac{sin(22)*147}{sin(135)}\\C=77.88\ ft$
