Answer:
Amount = £37
Step-by-step explanation:
Let Rose be represented by R.
Let Haydn be represented by H.
Given the following data;
Total amount = £250
Ratio of R:H = 2:3 = 2 + 3 = 5
To find how much Rose earned;
R = 2/5 * 250
R = 500/5
R = £100.
For Haydn;
H = 3/5 * 250
H = 750/5
H = £150
Next, we calculate the amount Haydn gave to charity;
Percent = 42% = 42/100 = 0.42
H = 0.42 * 150
H = £63
To find how much more Rose gave to charity than Haydn;
Amount = R - H
Amount = 100 - 63
Amount = £37
Answer:
r=5
Step-by-step explanation:
Circumference of a circle =
Since w are given that the circumference of circle is 31.4 cm
So,
[tex5= r[/tex]
So, radius of given circle is 5 cm
Area of circle =
=
=
Thus the area of circle is 78.5 sq.cm.
Hence the radius of given circle is 5 cm and the area of the circle is 78.5 sq.cm.
