The circumference of any circle is (pi) x (the diameter of the circle).
The problem gives you both numbers, so all you have to do is multiply them.
Circumference = (pi) x (diameter) = (3.14) x (21cm) = <span>65.94 cm .</span>
Answer:
- 920
Step-by-step explanation:
There is a common difference d between consecutive terms in the sequence, that is
d = 22- 30 = 14 - 22 = 6 - 14 = - 8
This indicates the sequence is arithmetic with sum to n terms given by
=
[ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = 30 and d = - 8 , thus
=
[ (2 × 30) + (19 × - 8) ]
= 10(60 - 152)
= 10 × - 92
= - 920
Answer:
2.
Step-by-step explanation:
The perimeter is 6 feet. So, Tina Does have enough
1) 4 blue : 20 total of jar 1 = 0.2
2) 25 blue : 100 total of jar 2 = 0.25
3) 0.2 + 0.25 = 0.45 - probability that a blue marble will be drawn from both jars
