What is the surface of a sphere with a radius of 13 units?
2 answers:
Sphere = 4PiRsquared
Radius = 13
13 x 13 = 169
169 x 4= 676 Pi
5e surface is 676Pi
Answer:
The correct answer is option B. 676π units²
Step-by-step explanation:
<u>Formula:-
</u>
The surface area of a sphere = 4πr²
Where r is the radius of sphere
<u>To find the surface area of given sphere
</u>
Here r = 13 units
Surface area = 4πr²
= 4 * π * 13²
= 4 * π * 169 = 676π units²
Therefore the correct answer is option A. 676 units²

Hi there!
The constant term would be 15.
A constant term is a term that does not or can not be changed.
Hope this helps !
Yes. 450 ÷ 9 = 50, 450 ÷ 5 = 90, 450 ÷ 10 = 45
