Answer:
The perimeter of the sector is :30.5 cm
Step-by-step explanation:
Mathematically, we have the area of the sector as;
e/360 * pi * r^2
r is 8 cm
so we have
58 = e/360 * pi * 8^2
58/64 * 360/pi = e
e = 103.85
To get the perimeter,
we have length of the arc plus 2r
Length of the arc is;
e/360 * 2 * pi * r
add 2 r;
e/360 * 2 * pi * r + 2r
so we have
103.85/360 * 2 * pi * 8 + 2(8)
= 14.5 + 16
= 30.5 cm
The answer is 40 because they're are 4 groups of ten so it would go like 10,20,30,and 40.=)
