HW Help

Hey....im having trouble with my math assignment.. i asked my sister for help but she couldn't get it either so i was wondering if you guys could help me out😛...here are hte problems:

PROBLEM 1

Figure:

Determine the length of the diagnol of a square that has an inscribed cricle with a circumference of 40(PIE)

(Hint: 1)determine the radius. 2)determine a side of the square. 3)use the pythagorean theorem or special triangle relationships to determine the diagnoal

Problem 2

How far will a wheel of radius 28 in. travel if it makes 240 revolutions

Problem 3

Figure:

Determine the area and circumference

Radius=6m.

Angle in Diagram=150*

Problem 4

In a circle of radius 10 in., determine the length of an arc of 144*

Problem 5

Figure:

Determine the circumference of the outside of this figure.

All arcs rae semi-circles in this diagram.

ABCD is a square whose area is 16m^2 (squared)

Please help me with this if you can😳

okk

r=20

nd diagonal of square = 40

Problem 2

How far will a wheel of radius 28 in. travel if it makes 240 revolutions

OMG.. use a calc. nd do

28 * 240

Problem 3

Figure:

Radius=6m.

Angle in Diagram=150*

4o(pie)=2(pie)r

so, r= 20

the side of a sq. is 40

so by using the pythagorean theorem,

40^2+40^2=C^2

C=56.57=the diagonal...and if u don't want it in decimals, simplify the sq.root of 3200
