A=πr squared.

9 divided by 2 = 4.5.

4.5 times 4.5 = 20.25.

A=(3.14) (20.25).

A=63.6.

Cable has 24 pennies he has hafe as many nickels as pennies he has 5 more dimes than nickels he has 6 fewer quarters than dimes

Andreyy89

Pennies (P) = 24
Nickels = 1/2P
Dimes = 1/2P + 5
Quarters = (1/2P + 5) -6

Therefore...

Nickels = 1/2P = 1/2(24)= 12
Dimes = 12 + 5 = 17
Quarters = 17 - 6 = 11

$\frac{(y2-y1)}{(x2-x1)}$

so just replace y and x for the proper values
