The formula for surface area of a sphere is A=4*PI*r^2
Using that formula and the known surface are we can find the radius. We can then use that to find the volume.
500 = 4*PI*r^2
Divide both sides by 4:
500/4 = PI *r^2
125 = PI *r^2
Divide both sides by PI
125/PI = r^2
39.79 = r^2
r = SQRT(39.79)
r = 6.3 cm
Now we can find volume using V=4/3*PI*r^3
V = 4/3 *PI *6.3^3
V= 1051.3
The answer is C

Step-by-step explanation:
Tiger Algebra gives you not only the answers, but also the complete step by step method for solving your equations 4x^2-2=38 so that you ... Step 2 : Step 3 :Pulling out like terms. 3.1 Pull out like factors : 4x2 - 40 = 4 • (x2 - 10) ... x2 = 10. When two things are equal, their square roots are equal.
62.4% x = 17.16 and the answer is 27.5.
The best way to explain it is to provide a couple of examples.
<u>Example 1:</u> 1.111 x 10³ multiplied by 5
= (1.111 x 5) x 10³
= 5.555 x 10³
<u>Example 2:</u> 6.666 x 10³ multiplied by 5
= (6.666 x 5) x 10³
= 33.330 x 10³
= 3.3330 x 10⁴
Answer: multiply the numbers together and then include 10ⁿ. Convert answer into scientific notation afterward, if needed.
Answer:
-6
Step-by-step explanation:
First we need to factorize the given expression
2x^2 - 5x - 3,
2x^2 - 6x+x - 3
The two number that we are going to use to split -5x are -6 and 1
Hence the required two numbers are -6 and 1
Let p = -6
Let q = 1
<h3>Taking their sum</h3>
p+q = -6 + 1 = -5
Take the product
p*q = -6 * 1
p*q = -6
hence the product is equal to -6
