Surface area of a sphere = 4πr^2
4πr^2=100π
Divide both sides by 4π
r^2=100
r=10
The radius is 10 cm.
Answer:
4.9h−2.7d−13
Step-by-step explanation:
Looking at the problem, what we must do to complete this question is to completely factor the expression that was provided. The expression that was provided is
.
The first step that we must do is to take a look at the expression and see what the two pieces of the expression have in common. We can see that both
and
have the number 5 and the variable c associated with them so we can factor out those two.
<u>Factor out 5c</u>
Now we have completely factored out the expression that was provided in the problem statement and we came to final answer of
.
Answer:
x = 10
Step-by-step explanation:
if there 2 same triangle then they are right triangle
By using Pythagorean theorem for 1 of right triangle, we have
=
+ 
74 = 49 + 
74 - 49 = 
25 = 
therefore, x =
=
= 10
