Answer:
t = 4.5
Step-by-step explanation:
Distribute 3 to the parentheses:
3(t + 4) = 25.5
3t + 12 = 25.5
Subtract 12 from both sides:
3t = 13.5
t = 4.5
So, the answer is t = 4.5

Answer: you square root it.
5r^2/5 = 80/5 =16
Sqr root of r^2=Sqr root of 16
r=4
Step-by-step explanation:
10(1/2x+6)=8
Is the equation. Hope this helped!
Answer:
111 cm^2
Step-by-step explanation:
h = 11.4
d = 5 so r (radius) = 2.5
Surface Area of a Cone Formula: πr^2 + πrs
s represents the slant height of the cone, lets represent this with a drawing.
We have the values of h and r, but we don't have the value of s, meaning we have to find it. We can do this by using pythagorean theorem.
a^2 + b^2 = c^2
These three values can come together to create a right triangle which we can seperate from the rest of the diagram, now we can find s.
s = √(11.4^2 + 2.5^2) so s = 11.67
now that we have all of the pieces, we can plug back into the original surface area formula. πr^2 + πrs
π(2.5^2) + π(2.5)(11.67) = 111.29 cm^2 or 111 cm^2
