Answer:
Radius = 2 cm.
Step by step explanation:
By the Pythagoras theorem the third side of the triangle
= sqrt (6^2 + 8^2)cm = sqrt100 = 10cm.
The formula for the radius of the circle is
r = sqrt [ (s - a)(s-b)(s-c)/ s ] where a,b,c are side lengths and s = the semi perimeter.
Here s = ( 6+8+10) / 2 = 12
So the radius r
= sqrt [ (12-6)(12-8)(12-10)/ 12 ]
= sqrt 4
= 2 (answer).
Let x represent the amount of dimes
Let y represent the amount of nickles
So since he has 20 coins, x + y = 20
and if we want to find the total money of dimes, we have to multiply x with 10
So 10x + 5y = 165 (in cents)
2x + y = 33
-x - y = -20
x = 13
so x = 13 and y = 7
Hope this helps :)
