Type the correct answer in the box. Assume that pi=3.14 and round your answer to the nearest integer.
stepan [7]

Answer:

648\ yd

Step-by-step explanation:

step 1

Find the circumference of the complete circle

The circumference is equal to

C=2\pi r

we have

r=35\ yd

substitute

C=2\pi(35)

C=70\pi\ yd

step 2

Find the measure of the arc length for a central angle of 280 degrees

Remember that the circumference subtends a central angle of 360 degrees

so by proportion

\frac{70\pi}{360}=\frac{x}{280}\\ \\x=280*(70\pi )/360\\ \\x=54.44\pi\ yd

step 3

Find the perimeter of the playground

P=54.44\pi+45=54.44*3.14+45=215.96\ yd

Multiply by 3

215.96*(3)=647.87\ yd

Round to the nearest integer

647.87=648\ yd

Solve for x. Round to the nearest tenth, if necessary.
natka813 [3]

Answer:

25.5

Step-by-step explanation:

first find angle E.

remember, all angles in a triangle always add up to 180 degrees.

E = 180 - 90 - 20 = 70 degrees

now we use the law of sines.

ED/sin(20) = DC/sin(70) = EC/sin(D)

EC = x

sin(D) = sin(90) = 1

24/sin(70) = x/1 = x

x = 25.5
