Answer:
50.24²
Step-by-step explanation:
Okay, so the formula for the area of a circle is π x radius² and we're just going to use 3.14 for π so:
We first have to find the radius, the radius is half the diameter:
8 ÷ 2 = 4
So 4 is our radius
4² = 16
3.14 x 16 = 50.24
So, the area of the circle is 50.24²
hope this helps:)

the complete question in the attached figure
we know that
sin40° = opposite side / hypotenuse
opposite side =AC
hypotenuse = AB-------> 10 in
so
sin 40=AC/AB---------> AC=AB*sin 40-------> AC=10*sin 40
the answer is
AC=10*sin 40
