Answer:
The answer is 200.96 cm^2.
2*3.14*r=50.24
=>r=50.24/6.28
=>r=8 cm
Thus area = 3.14*r*r
= 3.14*8*8
=200.96 cm^2
Step-by-step explanation:
A/Wall if you have 20 and 30 that box is missing # so you will need to times and you will get something like this 20×30=60 and that's the missing #

Answer:
<em>after 4seconds</em>
Step-by-step explanation:
Given the height, h , in feet, of the football above the ground after t seconds expressed by h ( t ) = − 8 t^2 + 32 t, the height of the ball on the ground is 0feet.
Substitute h(t) = 0 into the expression and calculate t;
h ( t ) = − 8 t^2 + 32 t
0 = − 8 t^2 + 32 t
8t² = 32t
8t = 32
Divide both sides by 8
8t/8 = 32/8
<em>t = 4s</em>
<em>Hence the football hits the ground after 4seconds</em>
Simply divide $10 by 4.5 to get the answer $2.22 per pound (actually the 2's keep repeating.
I guess the store might charge $2.23 since some will round any overage to the next penny.
