Answer:
20.25 m²
Step-by-step explanation:
the area (A) and circumference (C) of a circle are calculated using the formulae
C = 2πr and A = πr² ( where r is the radius )
calculate the radius using the formula for circumference
2πr = 9π ( divide both sides by 2π )
r = = = 4.5, hence
A = π × 4.5² = 20.25π m²
Answer:
5
Step-by-step explanation:
Add 6 to both sides. The answer is 5.
Answer:
87.4%
Step-by-step explanation:
The radius to the top of the atmosphere as a fraction of the moon's radius is ...
(2575 +600)/2575 ≈ 1.23301
The ratio of the moon's volume with atmosphere to the moon's volume without is the cube of this, or 1.87456
Then the ratio of the atmosphere's volume to the moon's volume is ...
(1.87456 -1)/1 = 0.87456
Atmospheric haze is about 87.4% of the moon's volume.
_____
We have assumed that the desired ratio is to the solid moon's volume, not the volume of moon and atmosphere together. The latter ratio would be 0.875 to 1.875 or about 46.7%.
Answer:
A
Step-by-step explanation:
320 portions of waffles can be made with one container.
Step-by-step explanation:
Given,
Milk is bought in 1 gallon container.
One portion of waffles require = 0.4 ounces of milk
We know that;
1 gallon = 128 ounces
Now;
No. of portions of waffles = ![\frac{Total\ ounces\ of\ milk}{Milk\ used\ per\ waffle}](https://tex.z-dn.net/?f=%5Cfrac%7BTotal%5C%20ounces%5C%20of%5C%20milk%7D%7BMilk%5C%20used%5C%20per%5C%20waffle%7D)
No. of portions of waffles = ![\frac{128}{0.4}](https://tex.z-dn.net/?f=%5Cfrac%7B128%7D%7B0.4%7D)
No. of portions of waffles = 320
320 portions of waffles can be made with one container.
