Answer:

7850 m^2

Step-by-step explanation:

The circumference of a circle is given by

C = 2*pi *r

314 = 2 * 3.14 *r

314 = 6.28 r

Divide each side by 6.28

314/6.28 = 6.28 r/6.28

50 m= r

Now we need to find the area

A = pi * r^2

A = 3.14 *r^2

A = 3.14 (50)^2

= 3.14 (2500)

7850 m^2

Answer:

(a) Arts take longer

(b) By 2/9 hours

Step-by-step explanation:

Given

Arts = four over nine hours

Maths = two over nine hours

Solving (a): Which takes longer?

First, represent both as fraction

$Arts = \frac{4}{9}\ hours$

$Maths = \frac{2}{9}\ hours$

Convert fraction to decimal

$Arts = \frac{4}{9}\ hours$

$Arts = 0.444\ hours$

$Maths = \frac{2}{9}\ hours$

$Maths = 0.222\ hours$

By comparison:

$0.444 > 0.222$

Hence, Arts take longer

Solving (b): How much longer?

To do this, we calculate the difference.

$Difference = Arts - Maths$

$Difference = \frac{4}{9} - \frac{2}{9}$

Take L.C.M

$Difference = \frac{4 - 2}{9}$

$Difference = \frac{2}{9}\ hours$
