$volume = \pi \times {r}^{2} \times h \\ volume = 3.142 \times (10 \div 2)^{2} \times 18 \\ volume \: = 3.142 \times 25 \times 18 \\ volume = 1413.9{cm}^{3}$

$price = \frac{1413.9 \times 0.02}{10} = 2.8278 = 2.83 \: dollars$

What is 1/4 as a whole number?

wlad13 [49]

The whole number of $\dfrac{1}{4}$ is $\boxed{0.25}.$

Further explanation:

Always use the PEDMAS rule to solve the grouping of multiplication, addition, subtraction and division.

Here, P is parenthesis, E is exponents, M is multiplication, D is division, A is addition and S is subtraction.

Given:

The number is $\dfrac{1}{4}.$

Explanation:

The whole numbers is the series of numbers that starts from zero.

The natural numbers are those numbers that start from one.

The place values are only natural numbers.

The base ten systems represent the position of a place value.

The given number is $\dfrac{1}{4}.$

Consider the number $\dfrac{1}{4}$ as $\text{A}$ .

$A = \dfrac{1}{4}$

Divide 1 by 4 to obtain the whole of $\dfrac{1}{4}.$

$\begin{aligned}\text{A}&= \frac{1}{4}\\&= 0.25\\\end{aligned}$

The decimal expansion of $\dfrac{1}{4}$ is $0.25.$

The whole number of $\dfrac{1}{4}$ is $\boxed{0.25}.$

In ΔPQR, the measure of ∠R=90°, the measure of ∠P=26°, and PQ = 8.5 feet. Find the length of QR to the nearest tenth of a foot.

Vitek1552 [10]

Answer:

3.7feet

Step-by-step explanations

Using the sin rule

A/sin a = B/sin b

Let A = PQ = 8.5feet

B = QR = x feet

a = R = 90°

b = P = 26°

Substitute the values into the Sin rule

8.5/sin90 = x/sin26

8.5×sin 26 = x × sin 90

8.5×0.4383 = x× 1

3.7255 = x

Hence the length of QR to the nearest tenth 3.7feet

The area of a circle is 28.26 square yards. what is the circle's circumference? a=28.26 yd2

Levart [38]

$area \: = \pi {r}^{2} \\ circumference = 2\pi \: r$
where r = radius
$\pi {r}^{2} = 28.26 \: {yd}^{2} \\ {r}^{2} = 28.26 \div \pi \\ {r}^{2} = 8.99 = 9 \\ \sqrt{ {r}^{2} } = r = \sqrt{9} = 3$
circumference = C
$c = 2\pi \: r = 2(3) \times \pi \\ = 18.85 \: yd = 18.9 \: yd$
