<u>Answer:</u>
1130400 km
<u>Step-by-step explanation:</u>
We know the formula for circumference of a circle:
<em>Circumference = 
</em>
So we need the radius of Saturn ring to calculate its circumference.
We are given Saturn's diamter which is 120,000km; and know that Saturn's ring extends for about 120,000 km from the circumference of the Saturn.
Therefore, the radius of Saturn's ring will be 120000 km plus half of the diameter of Saturn:
Radius of Saturn's ring = 120000 + (120000/2) = 180000 km
Circumference of Saturn's rings = 2 x 3.14 x 180000 = 1130400 km
Answer:
Step-by-step explanation:
So to define a recursive equation, you need to find how much each term is increasing or decreasing by. You also need to find the first term. To find the first term you can simply plug in 1 into x: 
. And as you can see the slope is 6, so each term is increasing by 6. So you get the recursive function:
In February, you have a balance of $270 in your bank account.In January, you have a balance of $270 - $45 = $225 in your bank account.In December, you have a balance of $225 - $45 = $180 in your bank account.
y = $180 + $45x, where x = 1, 2, 3, 4...
Balance in June: x = 6y = $180 + $45x = $180 + $45×6 = $180 + $270 = $450
Answer:
Part 1) The lateral area is 
Part 2) The surface area is 
,
Step-by-step explanation:
step 1
Find the lateral area of the cone
we know that
The lateral area of the cone is equal to
we have
substitute
step 2
Find the surface area of the cone
we know that
The surface area of the cone is equal to
we have
substitute
V = π r^2 (h/3)
(Volume equals pi r squared, h over 3)
Diameter is 4, so the radius is half of that = 2
Plug in the numbers
V = π (2^2) (16/3)
V = π (4) (5.333)
V = 3.14 x 4 = 12.566
V = 12.566 x 5.333
V = 67.014
