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

Day Drive 270 miles and 6 hours how many miles do you drive in 13 hours ​
NikAS [45]

Answer:

The answer is

<h2>585 miles</h2>

Step-by-step explanation:

In order to solve this question we use ratio and proportion

From the question

Day Drive 270 miles in 6 hours

So in order to find the distance drove in 13 hours, we compare the distance drove in 6 hours to the distance drove in 13 hours and solve

That's

if in 6 hours Day drove 270 miles

Then in 13 hours the person will drive

\frac{13  \times 270}{6}  =  \frac{3510}{6}

We have the final answer as

<h3>585 miles</h3>

Hope this helps you
