Explanation
The shaded area represents a segment. This can be solved with the formula below;
Since the triangle is an equilateral triangle, it implies that the angle subtended at the centre is 60 degrees. Also, the given radius is 7 cm

Answer:
Hi there!
The correct answer for you is 270.88.
To round to the hundreth's place (.0<u>1</u><u />), you need to take the number in the thousand's place (.00<u>1</u>), and determine if the number needs to go up or down.
If the number in the thousand's place is <u>greater</u> than 4, then the number goes up.
360.72<u>7</u> --> This means that the hundreth's number goes up to 3.
If the number in the thousand's place is <u>lesser</u> than 5, then that number stays the same.
89.85<u>2</u> --> This means that the hundreth's number stays the same.
After you round, then just subtract:
360.73 - 89.85 = 270.88.
I hope this helps!

Answer:
0
Step-by-step explanation:
=-5/6-7/6+2
=-12/6+2
=-2+2=0
.07×1.22 = ?
first take away the decimals in the question, 7×122 =854.
now add the decimals back to the answer, we had 4 decimal places in the questions so add 4 decimal places to 854 = 0.0854
answer= 0.0854
