Answer:

$Angle = 54$

Step-by-step explanation:

Given

Kano = 45;

Kwara = 410;

Ogun = 105;

Ondo = 126;

Oyo = 154

Total Distribution = 840

Required

Determine the angle subtended by Ondo (in a pie chart)

The general formula to calculate subtended angle in a Pie chart is;

$Angle = 360 * \frac{Frequency}{Total\ Frequency}$

In this case of Ondo

Frequency = 126

Total Frequency = Total Distribution = 840

Substitute these values in the given formula;

$Angle = 360 * \frac{126}{840}$

$Angle = \frac{360 *126}{840}$

$Angle = \frac{45360}{840}$

$Angle = 54$

<em>Hence, the angle subtended by Ondo is 54</em>

Answer:

18 jars can be filled completely.

Step-by-step explanation:

7L=7000ml

1 jar contain 375 ml

375ml can be filled in 1 jar

375ml=1 jar

1 ml = 1/375 jar

7000 ml = 7000× 1/375 jar

7000ml= 18.67 jar

hence 18 jars can be filled completely.
