If C (Circumfrence) = 314 m, what is the area?
1 answer:
Answer:
7850 m^2
Step-by-step explanation:
The circumference of a circle is given by
C = 2*pi *r
314 = 2 * 3.14 *r
314 = 6.28 r
Divide each side by 6.28
314/6.28 = 6.28 r/6.28
50 m= r
Now we need to find the area
A = pi * r^2
A = 3.14 *r^2
A = 3.14 (50)^2
= 3.14 (2500)
7850 m^2

Answer:
![\sqrt[3]{ \frac{1}{1000} {c}^{9} {d}^{12} } \\ = \frac{1}{10} {c}^{3} {d}^{4}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7B1%7D%7B1000%7D%20%7Bc%7D%5E%7B9%7D%20%20%7Bd%7D%5E%7B12%7D%20%20%7D%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B1%7D%7B10%7D%20%20%7Bc%7D%5E%7B3%7D%20%20%7Bd%7D%5E%7B4%7D%20)
400/12 = # of dozen needed
.89 * # of dozen needed
400/12=33.33 need 34 dozen
.89*34=$30.26
KE=0.5xmxv2
=0.5x 1.2x10^3x (3.4x10^3)^2=6936000000
