NEED HELP ASAP. <br><br> a sphere has a surface area of 36pi ft2. find the volume of the sphere.
max2010maxim [7]

Answer:

Approximately: 200.76π or 630.39

Step-by-step explanation:

Surface area for sphere formula: A = 4π(r^2)

36π = 4(r^2)

(36/4)π = [4(r^2)]/4

9π = r^2

28.26 = r^2 (since π equals 3.14)

√28.26 = √r^2

r ≈ 5.32

Volume for sphere formula: V = 4/3(π)(r^3)

V = 4/3(π)(5.32^3)

V ≈ 4/3(π)(150.57)

V ≈ 200.76π

or

V ≈ 630.39

I need help on question 7 and 8
DanielleElmas [232]
7.
remember
(ab)/(cd)=(a/c)(b/d)
we can split them up
and
(x^m)/(x^n)=x^(m-n)

\frac{27k^5m^8}{4k^3*9m^2}=  \frac{27k^5m^8}{36k^3m^2}=( \frac{27}{36} )( \frac{k^5}{k^3} )( \frac{m^8}{m^2} )=( \frac{3}{4})(k^{5-3})(m^{8-2} )=( \frac{3}{4})(k^2)(m^6 )= \frac{3k^2m^6}{4}



9.

2 to 3
4(x-1)=15
to
4x-1=15
the distribuutive prperty
a(b-c)=ab-ac
what he did was
a(b-c)=ab-c

he did not distribute the 4 to the -1


4(x-1)+3=18
minus 3
4(x-1)=15
distribute  4 to x and -1
4x-4=15
add 4 to both sides
4x=19
divide by 4
x=19/4
