I think it’s 175 but I might be wrong
Area of circle: A=pi×r². This area coresponds to 360degrees, or 2×pi radians.
2×pi ....... pi×r²
t radians....x
where t=2.75rads
Area of t: x=pi×r²×t/2/pi=r²×t/2
Area of t: 3²×2.75/2=9×2.75/2=12.375
Answer: the area of 2.75 radians is 12.375
I pretty sure the answer is 3.2 hours. I'm not completely sure though....
Answer:
I would say A. 7.8 x 10^-5
Step-by-step explanation:
7.8 x 10^-5 can also be written as 7.8 times 10 to the negative fifth power or the exponent of negative five. But, if you solve it you would get 0.000078 as the real number.
