Answer:

36π mi

Step-by-step explanation:

Area of a circle = πr²

Diameter = 12 mi. Therefore, radius=12/2 = 6 mi

πr²

π x (6)²

π x 36

Hence, the answer is 36π mi

!PLEASE HELP, THANK YOU!
icang [17]

Answer:

D

Step-by-step explanation:

you mean the formula is 4×pi×r² (not 4×pi/r²), right ?

then the correct answer is the sphere (ball).

the surface area of a cylinder is

top and bottom circle area = pi×r² each = 2×pi×r² both

and the mantle is 2×pi×r×height

the surface area of a block has nothing to do with pi.

it is the sum of 6 rectangles.

the surface area of a cone is

A = πr(r + sqrt(h² + r²))

again, also depending on "hight"

A^3b^2 divided by a^-1b^-3
Naya [18.7K]

Answer:

\frac{a^3 b^2}{\frac{1}{a} \frac{1}{b^3}}

And simplifying we got:

a^3 b^2 a b^3

a^3 a b^2 b^3 = a^{3+1} b^{2+3} = a^4 b^5

Step-by-step explanation:

We want to simplify the following expression:

\frac{a^3 b^2}{a^{-1} b^{-3}}

And we can rewrite this expression using this property for any number a:

a^{-1}= \frac{1}{a}

And using this property we have:

\frac{a^3 b^2}{\frac{1}{a} \frac{1}{b^3}}

And simplifying we got:

a^3 b^2 a b^3

a^3 a b^2 b^3 = a^{3+1} b^{2+3} = a^4 b^5
