Find the diameter and the circumference of the circle below r=8cm
vfiekz [6]

Answer:

diameter = 16cm, circumference ≈ 50.27

Step-by-step explanation:

The radius is 8 centimeters, so the diameter should be twice of that because the radius is the distance from the middle of the circle to the edge while the diameter is from edge to edge passing through the middle of the circle. Therefore,

8 · 2 = 16cm

The equation for the circumference of a circle is 2πr. In this case, because nothing else is specified about π, we use 3.14. So,

2 · 3.14 · 8 ≈ 50.27

Hope this helped! Have a great day. ^^

One card is selected at random from a deck of cards. determine the probability of selecting a card that is less than 99 or a spa
Kitty [74]
Since these events are independent, you add the possibilities

the number of cards less than 9 is 32
the number of spades is 13
there are 52 cards in a deck, so you put those numbers over 52

32/52 + 13/52 = 45/52

the answer is 45/52
