Find (a) the arc length and (b) the area of a sector.

Brut [27]

Answer:

a) 23.56 ft (2 dp)

b) 58.90 ft² (2 dp)

Step-by-step explanation:

Formula

$\textsf{Arc length}=r \theta$

$\textsf{Area of a sector}=\dfrac{1}{2}r^2 \theta$

$\quad \textsf{(where r is the radius and}\:\theta\:{\textsf{is the angle in radians)}$

Calculation

Given:

$\theta=\dfrac{3 \pi}{2}$
r = 5 ft

$\begin{aligned}\implies \textsf{Arc length} & =r \theta\\& = 5\left(\dfrac{3 \pi}{2}\right)\\& = \dfrac{15}{2} \pi \\& = 23.56\: \sf ft\:(2\:dp)\end{aligned}$

$\begin{aligned} \implies \textsf{Area of a sector}& =\dfrac{1}{2}r^2 \theta\\\\ & = \dfrac{1}{2}(5^2) \left(\dfrac{3 \pi}{2}\right)\\\\& = \dfrac{25}{2}\left(\dfrac{3 \pi}{2}\right)\\\\ & = \dfrac{75}{4} \pi \\\\& = 58.90 \: \sf ft^2\:(2\:dp)\end{aligned}$

i need you to explain your answer and show your work for me to have all 5 points! thank you so much and i hope you have a great

viktelen [127]

Answer:

42 cm ^2

Step-by-step explanation:

The area of a triangle is 1/2 B x H ( one half base times height)

The base is 6 cm and the height is 14 cm. So the full equation now is

1/2 (6) (14)

First you multiple 6 times 14 which is 84. Next you just divide it by 2 because 1/2 is half of the number. 84 divided by 2 is 42. So your answer is

42 cm ^2 (centimetres squared)

Algebraic Expression: The length of a rectangle is five inches less than triple the width. If the width is w inches, how long is

Montano1993 [528]

Answer:

l=(3w-5) Inches

Step-by-step explanation:

Let the width of the rectangle =w inches

The length of a rectangle is five inches less than triple the width.

Let us break the statement down into parts.

Triple the width=3w
Five inches less than triple the width =3w-5

Therefore, the length of the rectangle, l= (3w-5) Inches
