Assuming the radius is 5.4m. The exact length of an arc formed by a central angle measuring 60° is 1.8π or 5.65.
<h3>Length of an arc</h3>
Arc length of the circle=(theta)/360×pi×diameter
Diameter=2×radius
Where:
radius=5.4
Diameter=2×5.4=10.8
theta=60°
Arc length:
Arc length=60°/360°×π×10.8
Arc length=5.6548667765 or 1.8π
Inconclusion the exact length of an arc formed by a central angle measuring 60° is 1.8π or 5.65.

The average velocity of the bottle rocket are two given time intervals is 30 m/s and 20 m/s respectively, while the instantaneous velocity at 4.5 seconds is 22 m/s.
The given parameters;
- s(t) = -9t² + 103t + 403
- time interval (4.499, 4.5), and (4.5, 4.501)
The average velocity of the bottle rocket over the intervals is calculated as follows;
when the interval = [<em>4.499, 4.5</em>]


when the interval = [<em>4.5, 4.501</em>]

The instantaneous velocity of the bottle rocket at time t=4.5;

Thus, the average velocity of the bottle rocket are two given time intervals is 30 m/s and 20 m/s respectively, while the instantaneous velocity at 4.5 seconds is 22 m/s.

4(4x+5y) this should be the right answer
Answer:
1. Masaya, dahil alam ko na isa na naman itong masayang araw na makikita ko ang mga kaibigan ko. Ngayong nasa bahay na ay malungkot, dahil hindi ko makikita ang mga kaibigan ko at mas marami pang ipinapagawa.
2. Ang paaralan para sa akin ay isang masayang lugar kung saan ka mag aaral at makakakilala ng maraming kaibigan.
3. Ito ay parang paaralan nadin, ngunit hindi masaya at masigla tulad sa eskwelahan at hindi ko rin nakikita ang mga kaibigan ko.
4. Dahil malayo sa mga kaibigan, mas mahirap matuto online at dahil narin sa dahilang mas maraming pinapagawa kaysa dati.
5. Dahil walang sigla sa bahay at pahirapan ang paraan ng pag aaral ngayon.
