Convert 118 to radian measure.<br><br> Round your answer to the nearest hundredth.
dangina [55]

Answer:

2.06 rad

Step-by-step explanation:

To change degree measure to radian measure

radians = degrees × \frac{\pi }{180} , then

radians = 118 × \frac{\pi }{180}

            = \frac{118(\pi )}{180} ≈ 2.06 rad ( to the nearest hundredth )

Zahra has paper rectangles of different sizes. Every rectangle is 5 centimeters longer than it is wide. Is there a proportional
Alika [10]

Answer: The answer is NO. Explained below.


Step-by-step explanation:  Given that Zahra has a number of rectangles of different sizes which are made of paper. Also, the length of every rectangle is 5 cm more than its breadth.

We are to find whether the relationship between lengths and breadths of rectangles is proportional or not.

Let,  'l' represents the length and 'b' represents the breadth of any of these rectangles, then according to the given information, we can write

l = b + 5.

For a proportional relationship, we need a relation of the form

l = k × b, which is not always possible in the given case.

For example, if l = 8, b = 3, and l=9, b=4 then we cannot write

l = k × b, for a constant k.

Hence there is no proportional relationship  between the lengths and widths of these rectangles.

Thus, the answer is NO. Hence explained.

Use the Theorem of Pappus to find the volume of the solid formed by revolving the region bounded by the graphs ofy=x, y=10, and
Pepsi [2]

Answer:

C) 2094.40

nearest answer.

Step-by-step explanation:

Since the given region is bounded by y = x, y = 10 and x = 0

⇒ 0 ≤ y ≤ 10

Radius and Height are 'y'

∴ The required volume

= ∫₀¹⁰2π(radius)(height)dy

= ∫₀¹⁰2π (y) (y) dy

= ∫₀¹⁰2π y² dy

= 2π ∫₀¹⁰ y² dy

Integrate y

= 2\pi [\frac{y^3}{3}]_0^{10}

= 2\pi [\frac{10^3}{3} - 0]

= \frac{2000}{3} \pi

where π is 3.142

= 2,094.66
