The formula for area of a circle is π × radius², and the radius is half of the diameter, which means that your final expression is π × 6² = 36π = 113.1 inches². I hope this helps!
Answer:
x = 45
Step-by-step explanation:
0.36(18) + 0.04x = 0.12(24 + x)
6.48 + 0.04x = 2.88 + 0.12x
0.04x - 0.12x = 2.88 - 6.48
-0.08x = -3.6
0.08x = 3.6
x = 3.6/0.08
x = 45
Answer:
The answer is 97% decrease
Answer:
50.3
Step-by-step explanation:
area of a circle = πr²
where r = radius
given radius = 4yd
so we have A = πr²
==> plug in r = 4 ( because the given radius is 4yd )
A = π(4)²
==> evaluate exponent
A = 16π
==> simplify 16π
A = 50.3 ( rounded to the nearest tenth )
C. 6.1 units
its half of 12.2
