Answer:
11 sq.ft
Step-by-step explanation:
∅= 80×π/180= 4π/9
area= 1/2 × r²× ∅
= 1/2 × 16 × ∅
= 8∅
=8×(4π/9)
= 32π/9
= 11.17 ~11
Sry I really don’t know I would help but it got me confused
Answer: -96r + 13
1. distribute 8x2 - 8x12r
-3+8(2-12r)
-3+16-96r
2. add constants -3+16
-3+16-96r
13-96r
3. standard form
-96r + 13
Hal could be thinking of a number, 1437. Hope this helps! :)
