First find the circumference of the entire circle

C = 2*pi*r

C = 2*pi*4

C = 8pi

We have 3/4 of the circle so multiply the circumference by the fraction of the circle

3/4*8pi

6pi

Find the length and width of a rectangle. Perimeter = 50 Side A = 3x + 2 Side B = x - 5

zmey [24]

Step-by-step explanation:

Perimeter = 2 * (Side A + Side B)

= 2 * (3x + 2 + x - 5)

= 2 * (4x - 3)

= 8x - 6.

We have 8x - 6 = 50, so 8x = 56 and x = 7.

Length of rectangle = 3(7) + 2 = 23.

Width of rectangle = (7) - 5 = 2.

kykrilka [37]

Answer:

The answer is B.

Step-by-step explanation:

You have to apply the area of triangle formula :

$area = \frac{1}{2} \times base \times height$

$let \: base = 22 \\ let \: height = 3$

$area = \frac{1}{2} \times 22 \times 3$

$area = 11 \times 3$

$area = 33 \: {units}^{2}$
