The formula for the circumference of a circle = 2 x radius x pi
The radius is given as 21 cm and pi = 3.142
Circumference = 2 x 21 x 3.142 = 131.964 cm
Answer:
The rhinoceros iguana, which lives on the island of Hispaniola, lays up to 20 eggs in a burrow.
Step-by-step explanation:
Answer:
168 = L + 2W
And you want to maximize LW.
Which means you want to maximize W (168 - 2W), or 168W - 2W^2.
To maximize that, the derivative must go to zero.
0 = 168 - 4W, or W = 42. And L = 84. Done. :-)

Answer:
x= 25
Step-by-step explanation:
a²+b²=c²
24²+7²=c²
576+49= 625
√625= 25
