Find the area of the circle r=14m use pi=3.14 and round your answer to the nearest hundredth

pantera1 [17]

Answer:

<h2>The answer is 615 m²</h2>

Step-by-step explanation:

Area of a circle = πr²

where

r is the radius

From the question

r = 14 m

π = 3.14

The area of the circle is

A = 3.14 × ( 14 ) ²

= 3.14 × 196

= 615.44

We have the final answer as

<h3>615 m² to the nearest whole number</h3>

Hope this helps you

The area of the square is 100 square centimeters. What is the area of the circle?

Setler79 [48]

$length \: of \: 1 \: side = diameter$

$area \: = {l}^{2} \\ 100 = {l}^{2} \\ \sqrt{100} = l \\ l = 10$

$diameter = 2 \times radius \\ 10 = 2 \times radius \\ radius = 5$

$circle \: area = pi \times {r}^{2} \\ circle \: area = 3.142 \times {5}^{2} \\ circle \: area = 3.142 \times 25 \\ circle \: area = 78.55 {cm}^{2}$

Select the correct answer. what is the approximate solution to this equation? a. b. c. d.

Diano4ka-milaya [45]

The approximate solution to the given equation is x ≅ 148.4. The correct option is C. x ≈ 148.4

<h3>Solving equations</h3>

From the question, we are to determine the approximate solution to the given equation,

The given equation is

$4lnx -8 =12$

First, add 8 to both sides

$4lnx -8+8 =12+8$

$4lnx =20$

Now, divide both sides by 4

$ln x =\frac{20}{4}$

$ln x = 5$

Take the exponents of both sides

$e^{lnx} = e^{5}$

x = 148.413

x ≅ 148.4

Hence, the approximate solution to the given equation is x ≅ 148.4. The correct option is C. x ≈ 148.4
