The area of a circle is given by A=Pi*r^2, and its perimeter, P=2*Pi*r.

To get the radius r, you must divide 452.2 by Pi, and then calculate the square root of this quotient.

To get the circumference or perimeter, use the radius in the formula P=2*Pi*r.

Finally, round the number you get to the nearest tenth.

Devon set out to bicycle from Exeter to the beach, a distance for 10 miles. After going a short while at 15 miles per hour, the

enyata [817]

Answer:

Distance between Exeter and the point where flat tire occurred was 1.875 miles.

Step-by-step explanation:

Let the distance of Exeter and the point where bike developed the flat tire was = x miles

Then time taken to reach that point with speed 15 mi per hour = $\frac{\text{Distance traveled}}{\text{Time taken}}$

= $\frac{x}{15}$ hours

Devon comes back with a speed of 3 miles per hour then time taken to come back = $\frac{x}{3}$ hours

Total time for the entire episode = 48 minutes or $\frac{3}{4}$ hours

Therefore, $\frac{x}{15}+\frac{x}{3}=\frac{3}{4}$

$\frac{x+5x}{15}=\frac{3}{4}$

$\frac{6x}{15}=\frac{3}{4}$

x = $\frac{3}{4}\times \frac{15}{6}$

x = $\frac{15}{8}$ miles

x = 1.875 miles

Therefore, distance between Exeter and the point where flat tire occurred was 1.875 miles.

Even the measure ofAngle six is 62 what is the measure of angle five

Agata [3.3K]

<em>∠5 = 118</em>

Step-by-step explanation:

If you look closely at this image, you can see that ∠6 and ∠5 together will be equal to line c.

A straight line is equal to 180 so if we do...

$180-62$

= 118.

<u>∠5 will be equal to 118.</u>

If we go even further, because vertical angles are congruent...

∠7 = 62

∠8 = 118
