Help on 7 and 6 because I have something down with number six but I need help

Answer 1

What do you have to do

Answer 2

Find the area of the region
For six you have to do as=mARC/360 times pi times r^2 +2

Answer 3

no idea where you're getting that extra 2 from

but you have a right angle (90 degree) and a 40 degree angle
add them together and youll get the total arc that you can use to determine the area for 6

Answer 4

The two stands for the two sides that are shaded in which you have to add the whole equation with two

Answer 5

er no...

Answer 6

ok area for 6

Total area = area (40) + area (90)

Answer 7

I absolutely don't remember what my teacher said but something around those lines and that it is also half of the cirlce

Answer 8

for 7,

start with a circle with radius 8, then subtract the area of a circle with radius 6, then add the area of a circle with radius 4, then subtract the area of a circle with radius 2

Answer 9

How do I find the area of the circle for seven

Answer 10

Area = pi * r ^2

Answer 11

By the way where do I put the 5 inches for number six

Answer 12

5 is the radius, you need it to determine both the areas

Answer 13

Okay so like this... 130/360 times pi times 5^2

Answer 14

For 6

Answer 15
