What's choice B?

Answer 5

You there?

Answer 6

sorry yes

Answer 7

its 20%

Answer 8

Yep, you got it!

Okay, first we find the area of the big circle.

\(\sf r = 20\)

\(\sf A = \pi r^2\)

Plug in what we know:

\(\sf A = (3.14)(20)^2\)

Simplify exponent:

\(\sf A = (3.14)(400)\)

Multiply:

\(\sf A = 1256\)

Now find the area of a smaller circle.

\(\sf r = 4\)

\(\sf A = \pi r^2\)

Plug in what we know:

\(\sf A = (3.14)(4)^2\)

Simplify exponent:

\(\sf A = (3.14)(16)\)

Multiply:

\(\sf A = 50.24\)

There are 5 circles, so we multiply by 5 to find the area of all 5 circles.

\(\sf 50.24 \times 5 = 251.2\)

Now we divide this to the area of the big circle:

\(\sf 251.2 \div 1256 = 0.2\)

Multiply by 100 to convert it into a percentage:

\(\sf 0.2 \times 100 = 20\%\)
