Answer:
x = ± 6
Step-by-step explanation:
Given
x² - 72 = 0 ( add 72 to both sides )
x² = 72 ( take the square root of both sides )
x = ± 
= ± 
= ± 6
= 4
= -6

Answer:
you multiply all of those answers
Step-by-step explanation:
Answer:
S(r) = 3*π*r^(2)
V(r) = π*r^(3)/2
S(v) = 3*π* (cubic roof (2*V(r)/π)^(2)
Step-by-step explanation:
S(r) = lateral area + (area of base + area of top)
S(r) = 2*π*r*h + 2*π*r^(2) S(r) =2*π*r*r/2 + 2*π*r^(2) = π*r^(2) + 2π*r^(2)
S(r) =3*π*r^(2)
V(r) =π*r^(2)*h since h=r/2 V(r) =π*r^(3)/2
r^(3) = 2*V(r)/π r = cubic roof (2*V(r)/π)
And S(v) = 3*π* (cubic roof (2*V(r)/π)^(2)
Answer:
243
Step-by-step explanation:
1. 1/3 * 3 = 1
2. 1 * 3 = 3'
3. 3*3 = 9
4. 9*3= 27
5. 27*3 = 81
6. 81*3 = 243
7. 243
Hope this helps!
