Answer:
Radius of sphere is 3 units.
Step-by-step explanation:
Volume of sphere is given by
surface area of sphere is given by
where r is the radius of the sphere.
Given that
The number of cubic units in the volume of a sphere is equal to the number of square units in the surface area of the sphere.
we equate formula of Volume of sphere and surface area of sphere
assuming r as the radius.
thus,
Thus, radius of sphere is 3 units.
Answer:
4.5 cups of sugar
Step-by-step explanation:
This is how i solved it...
3 cups sugar = 48 pc. taffy
??? cups sugar = 72 pc. taffy
48 x 1.5 = 72
that means 3 x 1.5 should get you how many cups!
3 x 1.5 = 4.5
4.5 cups of sugar! hope this helps!!!
Answer:
Time taken = 9987.38 years
Step-by-step explanation:
We have plutonium-240 decays according to the parent function
k is the decay constant,0.00011
k = 0.00011
We need to find how long will it take 27 grams of plutonium-240 to decay to 9 grams.
Q(t) = 9 g
Q₀ = 27 g
Substituting
Time taken = 9987.38 years
Answer: V = 4.99482 cm^3
Explain: I used the formula V = m/p and found the density (p) of gold using the internet.
To nswer this you have to get a scientific calculator and multiply the number in the line of a and b times cos and then divide it for example the line a is 4.24 but when you multiply it by cos it is 0.997263104 and b is 3 but when you multiply by cos its 0.998629534, now divide 0.997263104 by 0.998629534 to get 0.998631694...
Hope this helps
