A triangle has an area of 240 square Inches. The height of the triangle is 15 inches. What is the length of the base of the tria
Alenkinab [10]

Answer:

32\:\mathrm{in}

Step-by-step explanation:

The area of a triangle is given by A=\frac{1}{2}\cdot b\cdot h.

Substituting given values, we have:

240=\frac{1}{2}\cdot b\cdot 15,\\480=15b,\\b=\frac{480}{15}=\boxed{32\:\mathrm{in}}

A circle has a central angle measuring startfraction 7 pi over 6 endfraction radians that intersects an arc of length 18 cm. wha
mash [69]

The radius of this circle is (B) 4.9 cm.

<h3>To find the radius of the circle:</h3>

To solve this problem, we need to, first of all, convert the angle from radians to degrees.

data;

  • length of an arc = 18cm
  • angle = 7/6π rads
  • π= 3.14

\frac{7\pi }{6rads} =210^{0}

Length of an Arc:

The formula for the length of an arc is given:

l_{arc} = θ/360 × 2\pi r

Let's substitute the values and solve:

18=\frac{210}{360} *2\pi r\\18=3.663r\\r=\frac{18}{3.663} \\r=4.9cm

From the calculations above, the radius of this circle is 4.9cm.

Therefore, the radius of this circle is (B) 4.9 cm.
