Answer:

226.8cm^2

Step-by-step explanation:

A=pir^2

24/4 = 6 (radius of small circles)

pi6^2= 113.097335529 times 2 (because theres 2 of them)

=226.8

24/2 = 12 (radius of big circle)

pi12^2= 452.4 minus 226.8 (to get the leftover space)

=226.8

kherson [118]

Answer: $\frac{9}{1}$

Step-by-step explanation:

FIrst find the square root of 81.

$\sqrt{81} = 9$

The square root of 81 is 9.

FInd the product of -1 and -3 by multiplying the -1 by -3.

-1 * -3 = 3

next find the square root of 4.

$\sqrt{4} = 2$

Combine and simplify the following radical expression.

guajiro [1.7K]

Answer:

Step-by-step explanation:

$2 \sqrt{20} + 8 \sqrt{45} - \sqrt{80}$

$= 2 \sqrt{2 \times 2 \times 5} + 8 \sqrt{3 \times 3 \times 5} - \sqrt{2 \times 2 \times 2 \times 2 \times 5}$

$= 2(2 \sqrt{5} ) + 8(3 \sqrt{5} ) - (4 \sqrt{5} )$

$= 4 \sqrt{5} + 24 \sqrt{5} - 4 \sqrt{5}$

$= 24 \sqrt{5} (ans)$
