Answer:

Relation between V and c is represented as:

V = \pi c^{3}

When c is halved, V becomes \frac{1}{8} of its initial value.

Step-by-step explanation:

Height of cylinder = Radius of cylinder = c

Volume of cylinder = V

As per formula:

V = \pi r^{2} h

Where r is the radius of cylinder and

h is the height of cylinder

Putting r = h =c

V = \pi c^{2} \times c\\\Rightarrow V = \pi c^{3} ......(1)

The values of c is halved:

Using equation (1), New volume:

V' = \pi (\dfrac{c}{2})^3\\\Rightarrow \dfrac{1}{8} \pi c^{3}

By equation (1), putting \pi \times c^{3}  = V

V' = \dfrac{1}{8} \times V

So, when c is halved, V becomes \frac{1}{8} of its initial value.

Find the circumference of the circle.
SashulF [63]

Answer:

  • The circumference of the circle in term of pi = 10π inches
  • The circumference of the circle us 3.14 as pi = 31.4 inches

Step-by-step explanation:

Given

The radius of the circle = r = 5 in

We know that diameter is twice the radius.

so d = 2r = 2(5) = 10 in

<u>Finding the circumference of the circle in terms of pi</u>

Using the formula to find the circumference of the circle

C = dπ

C = 10×π

C = 10π inches

Thus, the circumference of the circle in term of pi = 10π inches

<u>Finding the circumference of the circle using π = 3.14</u>

We know that the formula to find the circumference of the circle

C = dπ

Given

π = 3.14

substituting π = 3.14 to find the circumference of the circle

C = 10×3.14

C = 31.4 inches

Thus, the circumference of the circle = 31.4 inches

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.

Katie will have 7 dollars left over.

Step-by-step explanation:

100

She buys a book so subtract 23 from 100.

100-23= 77

Katie has 77 dollars and wants to donate $10 to as much charities. 10 can go into 77, 7 times, which means she can only donate to 7 charities in $10.
