Surface area of sphere equals its four radii squared multiplied by the number π.
We have then:
A = 4 * π * R ^ 2
Substituting:
804 = 4 * π * R ^ 2
Clearing the value of R we have:
R = root (804 / (4 * π))
R = 7.99876785 cm
Nearest whole number:
R = 8 cm
Answer:
The radius of a sphere is:
B. 8cm
Answer:
You would first put it into point slope form which is (y-y_1)=m(x-x_1). Then you would solve for y.
Answer:
It looks like the slope is -2
If the integers were all the same, then each one would be 1/3 of 138 = 46 .
They're not all the same, but they're consecutive, so you can find them easily.
Just start with your 3 copies of 46, take ' 1' away from one copy, and add it
to another one. You haven't changed their sum. You just made one of your
copies 1 less than 46, and you made another one of them 1 more than 46.
Now you have 45, 46, and 47, and that sure looks like an answer to me.
Isn't that easy ... you only had to use some brain instead of a lot of messy
algebra. That's what 'Brainly' might be all about, I guess.
