No don’t stab yourself! But I really hope someone helps you with this, I would but I just don’t understand sorry
We know that
length of a sector=[∅]*r--------> when ∅ is in radians
so
∅=length of a sector/r
for r=7 ft
length of a sector=4 ft
∅=4/7-----> 0.57 radians
the answer part 1) is 0.57 radians
part 2)
area of a sector=(∅/2)*r²--------> when ∅<span> is in radians
</span>area of a sector=(4/7/2)*7²-----> (4/14)*49----> 14 ft²
the answer Part 2) is 14 ft²
I Think It Is 3 x 8 x 4 = 96 But I Am Completely For Sure I Would Wait A Bit For Someone Else To Comment! Hope That Helps!!
Whenever you see <em>x </em> next to a 3, and it says that it equals 9, you know that 3•3=9.
