Find the area of the sector of a circle with radius 2 inches formed by a central angle of 4.3 radians: (in square inches)
1 answer:
Answer:
8.6 in²
Step-by-step explanation:
The area of the entire circle is A = πr², or A = π(2 in)².
This corresponds to a central angle of 2π radians, or 6.28 radians.
The area of the sector described above is just a certain fraction of that:
4.3 rad
-------------- * Area of circle = 0.685(4 * 3.14) = 8.6 in²
6.28 rad

213 - 102 = 111 miles from Praireville to Dorchester
1.5 inches for 300 miles.
300/50 = 6
So 6 x 1/4 = 6/4 AKA 1 1/2 AKA 1.5
1/5×m+2/3-2=m-2/5
Multiply both sides by 15:
3m+10-30=15m-6
12m=14
m=14/12
m=1.16
