nordsb [41]

Answer:

The pitcher plant's approximate volume is 24.492 \text{cm}^{3}.

Step-by-step explanation:

We are given that a  pitcher is shaped like a cylinder with a radius of 1 centimeter and a height of 7.8 cm.

Let the radius of a cylinder = r = 1 cm

and the height of a cylinder = h = 7.8 cm

As we know that the volume of a cylinder is given by;

The volume of a cylinder = \pi r^{2}h

                           = 3.14 \times 1^{2} \times 7.8  {taking approximate value of \pi to be 3.14}

                           = 3.14 \times 7.8

                           = 24.492 \text{cm}^{3}

Hence, this pitcher plant's approximate volume is 24.492 \text{cm}^{3}.

B=h+4, m=h-2  now we are told

b+h+m=11, using b and m found above in this equation gives us:

h+4+h+h-2=11

3h+2=11

3h=9

h=3 and since b=h+4, m=h-2

historical=3, biography=7, mystery=1

What number must be added to the expression below to complete the square?
stiv31 [10]

D. 1/4

Explanation:

a perfect square is written in the form

(x+a)^2 = x^2 + 2ax +a^2 (1)

In our problem, we have this perfect square:

x^2 - x + C (2)

with C being unknown. However, by comparing (1) and (2), we know that

2a=-1

So, we find

a=-\frac{1}{2}

and therefore, the missing term must be

a^2 = \frac{1}{4}

so the complete square is

x^2 -x +\frac{1}{4}
