Find the surface area of a bar of soap if the diameter is 5 cm and the height is 2cm .

Answers

Answer 1

Answer: Please see the pic, I'd solved in it.

Answer 2

Answer: Given that:
Diameter = 5 cm
which means,
Radius= $(diameter)/(2)$ = $(5)/(2)$ = 2.5 cm (radius is half the diameter)
and Height = 2 cm
We can assume that the shape is cylindrical

Formula of the Surface Area of a Cylinder
=2 $\pi$ r² + 2 $\pi$ rh
=2 $\pi$ (2.5)² + 2 $\pi$ (2.5)(2)
=12.5 $\pi$ + 10 $\pi$
=22.5 $\pi$ cm² (in terms of $\pi$ )
=70.69 cm² ≈ 70.7 cm²

A single die is rolled twice. Find the probability of rolling an Odd number the first time and a number greater than 4 the second time.

Answers

The probability of rolling an odd number the first time and a number greater than 4 the second time is 1/6

The sample space of a single die is

$\mathbf{S = \{1,2,3,4,5,6\}}$

So, the total sample is 6

The odd numbers are

$\mathbf{Odd = \{1,3,5\}}$ --- 3 odd numbers.

So, the probability of selecting an odd number is:

$\mathbf{P(Odd) = \frac 36}$

Simplify

$\mathbf{P(Odd) = \frac 12}$

The numbers greater than 4 are

$\mathbf{Greater = \{5,6\}}$ --- 2 numbers greater than 4.

So, the probability of selecting a number greater than 4 is:

$\mathbf{P(Greater) = \frac 26}$

Simplify

$\mathbf{P(Greater) = \frac 13}$

The probability of rolling an odd number the first time and a number greater than 4 the second time is calculated as follows:

$\mathbf{P = P(Odd) * P(Greater)}$

So, we have:

$\mathbf{P = \frac 12 * \frac 13}$

$\mathbf{P = \frac 16}$

Hence, the probability is 1/6

If log10(x^2y^3) =7 and log 10(x/y) =1 then x = blank and y= blank

Answers

From the second equation we get
$(x)/(y) =10$
Faim the first equation we get:
$x^2y^3=10^7$
We have $x=10y$ then
$(10y)^2y^3=10^7\ny^5=10^5\ny=10$
Then $x=10y=100$
