<h2>Answer:</h2>

<u>The radius of circle is </u><u>0.17 meters</u>

<h2>Step-by-step explanation:</h2>

Since Area of circle is given as

Area of circle = pi * r²

So putting the values

0.1 m² = 3.14 * r²

0.1 / 3.14 = r²

0.031 = r²

Taking square root on both sides

r = 0.17 metres

Answer:

5.64 cm

Step-by-step explanation:

1 decimeter = 10 centimeters

1 dm^2 = 10^2 cm^2 = 100 cm^2

Area of circle = 3.14*r^2 = 100

r2= 100/3.14*r^2 = 31.85

r = (31.85)^1/2 = 5.64 cm

Answer:

$28\frac{1}{2}\ papers$

Step-by-step explanation:

step 1

Convert mixed numbers to an improper fractions

$4\frac{1}{2}=\frac{4*2+1}{2}=\frac{9}{2}$

we know that

A teacher reviews 9/2 papers per hour

using proportion

Find how many papers will the teacher review in 19/3 hours

Let

x-----> the number of papers

$(9/2)/1=x/(19/3)$

$x=(19/3)(9/2)$

$x=28.5\ papers$

Convert to mixed numbers

$28.5=28\frac{1}{2}\ papers$
