Answer 3

thats the link of the pic

Answer 4

what is mc087-2.jpg?

Answer 5

I might just be misunderstanding the question. idk

Answer 6

ignore that

Answer 7

the pic to that question is this https://wcps6429-millbrookhs-ccl.gradpoint.com/Resource/3750901,780,111,0,0,0,0/Assets/testitemimages/geometry_b/area/mc087-1.jpg

Answer 8

The length of ac

Answer 9

WHAT IS THE LENGHT OF Measure angle AC

Answer 10

sorry lol

Answer 11

Arc Length = θ × r
(when θ is in radians)

Arc Length = (θ × π/180) × r
(when θ is in degrees)

θ is in degrees, so use that equation. θ is the angle between A and C.
I plugged it in and got 2pi. Let me know if that is what you get.

Answer 12

One circular table has a diameter of 9 ft, and another circular table has a diameter of 20 ft. How much greater is the area of the larger table? Round to the nearest whole number.

about 251 ft2
about 146 ft2
about 336 ft2
about 1,002 ft2

Answer 13

A team in science class placed a chalk mark on the side of a wheel and rolled the wheel in a straight line until the chalk mark returned to the same position. The team then measured the distance the wheel had rolled and found it to be 35 cm. To the nearest tenth, what is the area of the wheel?

27.5 cm2
97.5 cm2
195.1 cm2
390.1 cm2

Answer 14

i wanna know which one is the answers for both because me and two other people were getting diff answers

Answer 15

For the circular table one I got about 251ft^2.

I used A = pi * r^2
so, A1 - A2 = difference in area.

A1 = pi *(20/2)^2
A2 = pi * (9/2)^2
The difference in area is then 79.75 pi, or 250.542

Answer 16

For the second one, for the chalk mark to return to the same position the wheel must have made one full revolution. The distance rolled should be the circumference of the wheel.
Circumference of a circle = pi * diameter = pi * 2 * radius
Area of circle = pi * r^2

You have been given the circumference so solve for the radius and plug into the formula for the area of a circle.

Answer 17

I got 97.48 cm^2. If this isn't the answer you came to, what was your approach and answer?

Answer 18

97.5

Answer 19

Ok, awesome.

Answer 21

last one

Answer 22

I don't see a difference in that question versus the one you asked earlier. Same photo?

Answer 23

different photo

Answer 24

You are linking the same photo D:

Answer 25

same photo different measure angle

Answer 26

the first one was measure angle AC AND THIS ONE IS MEASURE ANGLE BAC
