Answer:
about 113.04 square inches
Step-by-step explanation:
No angles are indicated, so we must assume the sector is 1/4 of the circle. Then its area is 1/4 of that of a circle with radius 12 in:
Circle area = πr²
Sector area = (1/4)π(12 in)² = 36π in²
Sector area ≈ 36(3.14) in² = 113.04 in²
Answer:
the answer is 20 , the equation is 110=2f+2(2f-5)

Answer is 127 mm :)
because it's 12.7 cm,
so 127 mm
A(7)=1
a(20)=25
a(25)=?
a(n)=a(1)+d(n-1)
a(7)=a(1) +6d=1 -11/13+6*24/13=
a(20)=a(1)+19d=-25
a(1) +6d=1
a(1)+19d=-25 (subtract first equation from the second)
---------------------
19d-6d =-26
13d =-26
d=-2
a(1)=1-6d=1-6*(-2)=13
a(25)= a(1)+d(25-1)= 13+(-2) *24= 13-48=-35
