Answer:

12.56 $units^{2}$

Step-by-step explanation:

Area = $\frac{C*C}{4\pi }$

So, (12.56*12.56)/(4*3.14) results in $12.56^{2}$ /12.56 resulting in 12.56 units squared

Carlos has at most $40 to spend on food for a barbeque. He wants to buy hot dogs and hamburgers and then

poizon [28]

Answer:

$8.50

Step-by-step explanation:

I don't know what Alls are, but if Carlos insists, we can calculate how much he can spend on Alls with the expression:

($31.50) + r $\leq$ $40

This says the sum of what Carlos has already spent (hot dogs and hamburgers) plus the amount he spends on Alls (rolls?), r, must be equal to or less than the $40 he has allowed himself to spend.

($31.50) + r $\leq$ $40

r $\leq$ $40 - $31.50

r $\leq$ $8.50

Answer:

Step-by-step explanation:

sin2x = 2sinx*cosx

= $2\sqrt{sin^{2}x }$ * cosx

= $2\sqrt{(1-cos^{2}x }$ * cosx

= 2 $\sqrt{1-\frac{3}{5} ^{2} } *\frac{3}{5}$

= $\frac{8}{5} * \frac{3}{5}$

= 24/25
