I need some help finding the volume of a sphere with a diameter of 18.6cm. The website says the answer I got from my calculator was wrong! Help would be greatly appreciated!
Answers
Answer:
V ≈ 3367.6 cm³
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V = [tex]\frac{4}{3}[/tex] πr³ ( r is the radius )
Here D = 18.6 , then r = 18.6 ÷ 2 = 9.3 , so
V = [tex]\frac{4}{3}[/tex] × 3.14 × 9.3³
= [tex]\frac{4}{3}[/tex] × 3.14 × 804.357
= [tex]\frac{4(3.14)(804.357)}{3}[/tex]
≈ 3367.6 cm³ ( to the nearest tenth )

Solve log 2x^2 + 2 = 6. Round to the nearest thousandth if necessary.
Answers
Answer:
x = 70.71
Step-by-step explanation:
log 2x² + 2 = 6.
log 2x² + log 100= log 10⁶.
2x² × 100 = 10⁶
2x² = 10⁶/100
2x² = 10⁴
x² = 10⁴/2
x² = 5000
x = √5000
x is approximately 70.71
x = 70.71

Susan has a weight of 40.65 kilograms. Adam is 4.3 kilograms heavier than Susan, and James is 2.9 kilogram lighter than Susan. What are the weights of Adam and James combined?Immersive Reader
Answers
Answer:
82.7kg
Step-by-step explanation:
wdym by immersive reader?
Answer:
82.7kg
Step-by-step explanation:
We know that Susan is 40.65kg. If Adam weighs 4.3kg more than Susan, it means that he weighs 40.65+4.3 = 44.95kg
James is 2.9kg lighter meaning he is 40.65-2.9 = 37.75kg
Now that we know that weights of Adam and James (44.95 and 37.75). we can add them together to get the combined weight: 44.95 + 37.75 = 82.7kg

Volume of cuboid = 300 in³
Surface area of cuboid = 280 in²
Step-by-step explanation:
Given:
Length = 10 in
Width = 5 in
Height = 6 in
Find:
Volume of cuboid
Surface area of cuboid
Computation:
Volume of cuboid = [L][B][H]
Volume of cuboid = [10][5][6]
Volume of cuboid = 300 in³
Surface area of cuboid = 2[lb][bh][hl]
Surface area of cuboid = 2[(10)(5) + (5)(6) + (6)(10)]
Surface area of cuboid = 2[50 + 30 + 60]
Surface area of cuboid = 2[140]
Surface area of cuboid = 280 in²
Answer:Volume of cuboid = 300 in³
Surface area of cuboid = 280 in²

After rain, water flows over the Sutherland Falls at a rate of 74240 litres per second. This is an increase of 45% on the rate before the rain. Calculate the rate before the rain.
Answers
Answer: 51,200 litres per second
Step-by-step explanation:
Assume that the rate before the rain is denoted as x.
This would mean that 74,240 liters per second is an increase of 45% over the value of x.
In formula form therefore this is:
74,240 = x + (x * 45%)
74,240 = x + 0.45x
74,240 = 1.45x
x = 74,240 / 1.45
x = 51,200 litres per second

Luna Lovegood is making smoothies for the Ravenclaw students. She combines two and a half quarts of orange juice, four and a half pints of milk, and 5 cups of pineapple juice to make the smoothies. How many cups of smoothie does Luna make? *
Answers
Answer: Luna Lovegood made 24 cups of smoothie.
Step-by-step explanation: We have to convert the measurements to cups.
Orange Juice:
2 1/2 quarts converted to cups is 10 cups.
2 1/2 or 2.5 multiplied by 4 equals to 10
Milk:
4 1/2 or 4.5 pints converted to cups is 9 cups.
You have to do 4.5 times 2 to get 9.
Pineapple Juice:
5 cups. Since it's already been converted we don't do anything to convert.
Lastly, we add.
10+9+5=24 cups.
Answer:
Let me go ask LunaLovegood555..... she's good at making smoothies.
Step-by-step explanation:

At a bus station, buses begin their routes at 6.Am. The schedule for two of the buses is based on time intervals listen below
Answers
Answer:
They will both leave at 07:15am
Step-by-step explanation:
Given
[tex]Start\ time = 6:00am[/tex]
[tex]Bus\ A=75\ mins[/tex]
[tex]Bus\ B=15\ mins[/tex]
Required
Next time both buses leave the station at the same time
To do this, we list out the multiples of 75 and 15.
We have:
[tex]Bus\ A = 0,75, 150, 225, 300,375, 450, 525, 600 ....[/tex]
[tex]Bus\ B =0, 15,30,45,60,75,90,105,120,135,150,165,180.....[/tex]
After the first departure at 06:00 am (0 minutes) for both buses respectively, the next time they both leave is after 75 minutes (common multiple)
So, the time is:
[tex]Time = 6:00am + 75 mins[/tex]
[tex]Time = 07:15am[/tex]
