For slope-intercept form it's y=-2x+2 and for point-slope form the answer is y-18=-2(x-(-8)) or y-18=-2(x+8).

Use the fact that the length of an arc intercepted by an angle is proportional to the radius to find the arc length given that r

Komok [63]

Answer:

The required length is 37.68 cm

Step-by-step explanation:

We have given the radius of which is 3 cm and $\theta$ which is $\pi\cdot 4$

We will use $\pi=3.14$

We know the formula for length of arc which is:

length of arc=radius x angle

We will substitute the values given we will get:

$length=3(3.14)(4)$

$length=37.68$

Hence, the required length is 37.68 cm

Find the total surface area of this triangular prism base=5cm 9cm line in the middle 12cm width=20cm 2 lengths on triangle 13cm

nikklg [1K]

We have been given an image of a triangular prism. We are asked to find the total surface area of the the prism.

The total surface area of the prism wold be sum of areas of all faces.

First of all, we will find the area of base and other two rectangles on sides.

$\text{Area of base}=(5+9)\times 20$

$\text{Area of base}=14\times 20=280$

$\text{Area of other two rectangular faces}=15\times 20+13\times 20$

$\text{Area of other two rectangular faces}=300+260$

$\text{Area of other two rectangular faces}=560$

Now we need to find the area of two triangular faces.

$\text{Area of other two triangular faces}=2\times \frac{1}{2}\times (5+9)\times 12$

$\text{Area of other two triangular faces}=14\times 12$

$\text{Area of other two triangular faces}=168$

$\text{Total surface area}=280+560+168$

$\text{Total surface area}=1008$

Therefore, the total surface area of the prism is 1008 square cm.
