Answer:

1) P=4s

2) P=4\sqrt{A}

see the explanation

Step-by-step explanation:

we know that

The perimeter of the square is equal to

P=4s

where

s is the length side of the square

we have

P=15,2\ cm

substitute

15.2=4s

solve for s

s=15.2/4=3.8\ cm

The area of a square is equal to

A=s^2

substitute

A=3.8^2=14.44\ cm^2

we have that

s=\sqrt{A}

therefore

2 equations that can determine the perimeter of the square are

1) P=4s ----> P=4(3.8)=15.2\ cm

2) P=4\sqrt{A} ----> P=4\sqrt{14.44}=15.2\ cm

PLS HELP ASAP! Given a cone with a height of 6 cm and a base diameter of 6 cm, what is the volume of the cone? Use 3.24 for π
Sholpan [36]

Answer:

56.52 cm³

Step-by-step explanation:

\boxed{volume \: of \: cone =  \frac{1}{3} \pi {r}^{2}h }

Diameter= 2 ×radius

Radius

= 6 ÷2

= 3cm

Height, h= 6cm

Volume of the cone

=  \frac{1}{3} (3.14)( {3}^{2} )(6)

= 56.52 cm³

Beth gets a sum of 5 when she rolls two fair number cubes. What is the probability that one of the fair number cubes is a 1?
ira [324]

Using it's concept, it is found that there is a 0.5 = 50% probability that one of the fair number cubes is a 1.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

The outcomes of the pair of cubes that result in a sum of 5 are as follows:

(1,4), (2,3), (3,2), (4,1).

Of those 4 outcomes, 2 involve a number 1, hence the probability is given by:

p = 2/4 = 0.5.
