Answer:

The correct option is b.

Step-by-step explanation:

The area of a rectangle is

A=length\times width

The area of rectangle is 48 square units and the width of the rectangle is 6 units.

48=length\times 6

Divide both sides by 6.

8=length

The length of the rectangle is 8.

In a right angled triangle,

\tan\theta=\frac{perpendicular}{base}

In triangle JKL,

\tan (\angle KLJ)=\frac{JK}{KL}

Opposite sides of a rectangle are same.

\angle KLJ=\tan^{-1}(\frac{6}{8})

\angle KLJ\approx 36.87

The measure of angle KLJ is 36.87. Therefore the correct option is b.

Find the area of a triangle with a base length of 3 units and a height of 4 units. 3 square units 6 square units 7 square units
yan [13]

For this case we have that by definition, the area of a triangle is given by:

A = \frac {b * h} {2}

Where:

b: It is the base of the triangle

h: It is the height of the triangle

According to the data of the statement we have:

b = 3 \ units\\h = 4 \ units

Substituting in the formula we have:

A = \frac {3 * 4} {2} = \frac {12} {2} = 6 \ units ^ 2

So, the area of the triangle is6 \ units ^ 2

Answer:

6 \ units ^ 2

The diameter of a cylinder is 4 centimeters. The height is 12 centimeters. Using 3.14 for pi, what is the volume of the cylinder
erica [24]

Answer:

V = 150.72 cm³.

Step-by-step explanation:

First, get the volume of a cylinder.

V = πr²h

Where:

π = 3.14 (given)

r = radius (half of diameter, or 2)

h = height (12)

Knowing this, substitute the known values.

V = πr²h

V = (3.14)(2²)(12)

Square 2.

V = (3.14)(4)(12)

Multiply 3.14 and 4.

V = (12.56)(12)
Multiply 12.56 and 12.

V = 150.72.

Since it is already rounded to the nearest hundredth, that is your answer.
