Answer:
178.5 m^2
Step-by-step explanation:
Here we see a square and a half circle
Equation: A=bh+πr²
Square: 10*10= 100
Half circle: π5² (it is 5 because the diameter is 10)
A= 25π
A=100+25π
A=178.5
The applicable identity is ...
... cos(a)cos(b) = (1/2)(cos(a+b) +cos(a-b))
Let a=36t, b=6t and substitute this into your expression. Then you have ...
... 20cos(36t)cos(6t) = 20·(1/2)(cos(36t+6t) + cos(36t-6t))
... = 10(cos(42t) + cos(30t))
... = 10cos(42t) +10cos(30t)
1. You can solve this problem and calculate the volume of the cooler, by following the proccedure below:
2. You have that the cooler measures <span>1 1/2 feet by 1 foot by 1 1/5 feet; then, you only have to multiply these values. Then, you have:
1 1/2 feet=1.5 feet
1 1/5 feet=1.2 feet
Volume of the cooler=(1.5 feet)(1 foot)(1.2 feet)
Volume of the cooler=1.8 feet</span>³
<span>
What is the volume of the cooler?
The answer is: T</span>he volume of the cooler is 1.8 feet<span>³</span><span>
</span>
