Answer:

$18\pi\ cm^2$

Step-by-step explanation:

step 1

Find the area of complete circle

The area of the circle is given by the formula

$A=\pi r^{2}$

we have

$r=9\ cm$

substitute

$A=\pi (9)^{2}$

$A=81\pi\ cm^2$

step 2

Find the area of the shaded region

we know that

The area of complete circle subtends a central angle of 360 degrees

using proportion

Find out the area of the shaded region if the central angle is equal to 80 degrees

$\frac{81\pi}{360^o}=\frac{x}{80^o}\\\\x=81\pi(80)/360\\\\x= 18\pi\ cm^2$

Show how to make a ten to solve 13-7. Write the number sentence.

VARVARA [1.3K]

-7 + 3 + 10 = -4 + 10 = 10 - 4 = 6.

To turn 13 into 10, you need to break it up into 10 + 3, which does not change the value of 13. Then, you add 3 to -7, which results in -4. Next, you add -4 to 10 (or rather, subtract 4 from 10), which results in 6.
