For 5! you can just put it in a calculator of any sort but if you want to to the work you multiply every number before it like 5*4*3*2*1 and this equals 120.
Answer:
<em>13π/9 rad</em>
Step-by-step explanation:
Given the following
Area of a sector = 26πcm²
radius of the sector = 6cm
Required
central angle measure of the sector in radians
Area of a sector = Ф/2π * πr²
26π = Ф/2π * πr²
26 = Ф(6)²/2π
26 = 36Ф/2π
2π = 36Ф/26
π = 18Ф/26
26π = 18Ф
Ф = 26π/18
<em>Ф = 13π/9 rad</em>
<em>Hence the measure of the central angle in radians is 13π/9 rad</em>
Answer:
No
Step-by-step explanation:
Two possible answers for x could be -4 or -10/3. Neither of those are close to 5. Therefore, the answer is no.
