Answer: 8π mm (in terms of π)
Step-by-step explanation:
1) The formulas for solving the circumference of a circle is πd (π times diameter).
2) 8 times π equals 8π mm.
Hopes this helps!
Answer:
Step-by-step explanation:
we know that
The rule to calculate the a_n term in an arithmetic sequence is
where
d is the common difference
a_1 is the first term
n is the number of terms
we have
Remember that In an Arithmetic Sequence the difference between one term and the next is a constant. and this constant is called the common difference
so
Find the 96th term of the arithmetic sequence
we have
substitute
Because you need 100 feet of fencing to go all the way around, the circumference of the rectangle is 100.
Then, because this is a rectangle, both sides of the length are equal and both sides of the width are equal.
Therefore, we can represent the circumference with the following equation:
100=2(30)+2x, where x is the width.
Then we solve for x be rearranging the equation.
First simplify:
100=60+2x
Then subtract 60 from both sides
40=2x
Then divide both sides by 2
20=x
Therefore, the width of the garden is 20 feet.
Answer:
Step-by-step explanation:
3x + y + 72 = 180
3x + y = 108 .... <em>(1)</em>
2x + y = 90 ..... <em>(2)</em>
(1) - (2)
<em>x = 18°</em>
<em>y = 54°</em>
