1/10 because amongst 10 balls there is only one 10th ball there by making only one possible chance of getting ball no 10
Formula: 1/2(πr²)
radius: 14/2=7
1/2(π x 7²)
So the Surface Area is: 76.96902001. Round it to the decimal point u want
The angles form a right angle, so make an equation where they add up to 90 degrees.
(c + 3) + (4c - 13) = 90
Combine like terms.
5c - 10 = 90
Add 10 to both sides.
5c = 100
Divide both sides by 5.
c = 20
Answer:
34.54 
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Height (h) = 3.7 km
Base radius (r) = 3 km
We can calculate the volume of mountain by using following formula,
So, volume of cone = (1/3)π
h
By putting the value in the formula, we get
= (1/3) π × 
× 3.7
= 11.1π
= 34.54
Hence, the volume of the mountain is 34.54 .
Answer:
700 ml
Step-by-step explanation:
If the 15cm bottle holds 500ml of water, you can create the ratio of 15:500, which simplifies to 3:100.
Since the second bottle is 21cm, you find 21:x.
Because you already have 3:100 as given from the first bottle, if you multiply both sides by 7 you get 21:700.
This means the second bottle holds 700ml.
