So you you are trying to find the area of sphere so you would use this formula
A=4•3.14•r^2
And you already know that the radius is 6 so you would go ahead and plug in the numbers
A=4•3.14•4^2
4^2 is 16 so your final equation would be
A=4•3.14•16
And your answer is
=452.39

Answer:
75.02 ft
Step-by-step explanation:
Split the problem into 2 different part. The bottom part of the tree is 5 feet because that's where your eye levels are, so you just have to solve the top part of the tree.
The top part of the tree is solved by finding the height of the triangle. If you remember SohCahToa, the opposite side of the angle is solved using tangent.
tan(angle) = opposite/adjacent
tan(35) = x/100, x is just the unknown height of the tree.
multiply 100 on both side to get x by itself.
x = 100tan(35)
x = 70.02
add that top height of the tree(70.02ft) with the bottom height of the tree(5ft).
70.02+5 = 75.02 ft
Answer:
After 5 months the cost of the two phones and monthly service be the same.
Step-by-step explanation:
1st service cost = $50 + $40x, where "x" represents the number of months
2nd service cost = $50x
Now we have to find the number of months the cost of the two phones and monthly service be the same.
Now we have to equivate and find the value of x.
50x = 50 + 40x
Subtracting 40x from both sides, we get
50x - 40x = 50 + 40x - 40x
10x = 50
Dividing both sides by 10, we get
x = 50/10
x = 5
After 5 months the cost of the two phones and monthly service be the same.
Hope you will understand the concept.
Thank you.
