Answer:
2A/r + 2r
Step-by-step explanation:
A sector is made of an arc and two radii. As such, the perimeter of the sector is the sum of the length of an arc and the two radii. Given that the radius is r and the area is A, the area of a sector A
= Ф°/360° * πr²
The length L of an arc of the sector
= Ф°/360° * 2πr
Hence,
A/L = r/2
L = 2A/r
The perimeter of the sector
= L + 2r
= 2A/r + 2r
You are given
the distance of the horse of 45 miles at 15miles per hour and another 35 miles
at 10 miles per hour. You are asked the total time in hours of the cowboy
riding his horse. You have to get the time each mile the cowboy rode.
45 miles/15
miles per hour = 3 hours
35 miles/10
miles per hour = 3.5 hours
<span>3 hours + 3.5
hours = <u>6.5 hours</u>
</span>
<span>So the answer
is B. 6.5 hours.</span>
Answer:
6,428
Step-by-step explanation:
solo usa una calculadora o una hoja de papel
Espero que esto te ayude y que tengas un gran dia.
To find how many miles per hour, we divide the number of miles hiked by the number of hours it took to hike them.
=15.12 miles ÷ 6.3 hours
=2.4 miles hiked per hour
Hope this helps! :)
Triangle ABC is congruent to triangle CDE using the side - angle - side congruence theorem. The sink hole is 52.2 ft and the Perimeter of ABC is 172.2 ft
<h3>What are
congruent triangles?</h3>
Two triangles are said to be congruent if they have the same shape and their corresponding sides are congruent.
In the image shown:
AC = CE, BC = ED and they have the same angle (opposite angles are congruent).
Hence:
Triangle ABC is congruent to triangle CDE using the side - angle - side congruence theorem.
AB = DE = 52.2 ft
Perimeter of ABC = AB + BC + AC = 50 + 70 + 52.2 = 172.2 ft
