Answer:
![63.63 {m}^{2}](https://tex.z-dn.net/?f=63.63%20%7Bm%7D%5E%7B2%7D%20)
Step-by-step explanation:
![area \: = \pi {r}^{2} \\ = 3.142(4.5) {}^{2} \\ = 63.63m {}^{2}](https://tex.z-dn.net/?f=area%20%5C%3A%20%20%3D%20%5Cpi%20%7Br%7D%5E%7B2%7D%20%20%5C%5C%20%20%3D%203.142%284.5%29%20%7B%7D%5E%7B2%7D%20%20%5C%5C%20%3D%2063.63m%20%7B%7D%5E%7B2%7D%20)
The missing length is 12km (i never promised anything xd)
I'm glad to hear that, but where is the math problem?
Answer:
$199.50
Step-by-step explanation:
10% discount of $34 = 10/100*34 = $3.40
so, a single shirt costs $34-$3.40 = $30.60
half off = 50% discount of $31 = 50/100*31 = $15.50
so, a single cap costs $31-$15.50 = $15.50
so, 5 shirts and 3 caps cost now
5*$30.60 + 3*$15.50 = $153 + $46.50 = $199.50
but careful - can this be a trick question ?
the phrasing of the problem description can also suggest that the discounts are only listed to confuse us and are already included in the mentioned prices ("worth" $34 - what does that mean ? because including the discounts they are currently "worth" their prices).
then it would just plainly be
5*$34 + 3*$31 = $170 + $93 = $263
