Answer:
Step-by-step explanation:
The circumference of a circle is the perimeter or the distance around the circle. It is calculated using the following formula:
The diameter of the circle is 15 centimeters. We are asked to use 3.14 for pi.
Substitute the values into the formula.
Multiply.
This number only has numbers in the tenth place, so we don't need to round.
The circumference of the circle is <u>47.1 centimeters.</u>
Answer:
Step-by-step explanation:
A fraction exponent converts into a radical. The denominator is the index of the radical (farthest left number) and the numerator is the exponent of the base inside (the farthest right number). The base of the fraction exponent is the base number in green. To write this expression, simply the exponents into one exponent and one base.
Now convert to the radical.
Answer:
a₆ = 6
Step-by-step explanation:
There is a common ratio r between consecutive terms in the sequence, that is
r = =
=
= -
This indicates the sequence is geometric.
To obtain any term in the sequence, multiply the previous term by r, thus
a₅ = 216 × - = - 36
a₆ = - 36 × - = 6
