Answer:

Option B. 134.58 cm²

Step-by-step explanation:

Since one of a triangle with two sides and angle opposite to the third side is represented by area = \frac{1}{2}(a.c sinθ)

Since a = 14 cm

          c = 20 cm

  and  θ = 74°

By putting thee values in the formula

Area =  \frac{1}{2} (20) (14) (sin74°)

        = 140(0.9613)

        = 134.58 cm²

Therefore, option B is the answer.

Eli needs pieces of ribbon cut into strips that are 2 1/2 feet long. The roll of ribbon is 7 1/2 feet long. Which expression cou
Lady bird [3.3K]

3 strips of 2.5 feet can be cut from the 7.5 feet long roll of ribbon.

Step-by-step explanation:

<u>DATA:</u>

Length of strips Eli need is 2.5 feet long

Length of roll of ribbon is 7.5 feet long

Number of strips that can be cut from the 7.5 feet long roll is x

<u>SOLUTION:</u>

To determine how many strips can be cut, divide total length of roll of ribbon by the length of strips needed.

Number of strips that can be cut = \frac{Total Length of roll}{Length of strips needed}

x = \frac{7.5}{2.5}  (expression)

x = 3 strips

Therefore, 3 strips of 2.5 feet can be cut from the 7.5 feet long roll of ribbon.

The volume of a cone is 50 pi cubic feet. Its height is 6 feet. In feet, what is the radius of the cone? Round the answer to the
prohojiy [21]

Answer:

The radius of the cone is 5\ ft

Step-by-step explanation:

we know that

The volume of a cone is equal to

V=\frac{1}{3}\pi r^{2}h

In this problem we have

V=50\pi\ ft^{3}

h=6\ ft

substitute in the formula and solve for r

50\pi=\frac{1}{3}\pi r^{2}(6)

Simplify

25=r^{2}

square root both sides

r=5\ ft
