Surface area = 4πr²
⇒ 400 = 4 * 3.14 * r²
⇒ r² = 400/12.56
⇒ r² = 31.84
⇒ r = √31.84 = 5.64 inches
Answer is A.
Hope it helps!
Answer:
$5.50
Step-by-step explanation:
k lets say x=movies while y=games
so, lets make a system of equations
2x+3y=14.50
3x+y=9.50
you can do substitution or elimination here it doesn't matter but you get x=2; y=3.5
movies cost 2 bucks, while games cost $3.50
so total is 3.50+2
if you still want instruction on how to solve a system of equations leave a comment and i'll help
Answer:
x = 42,33°
Step-by-step explanation:
3x + 1° + 52° = 180° [<em>angles</em><em> </em><em>on</em><em> </em><em>a</em><em> </em><em>straight</em><em> </em><em>line</em><em>]</em>
3x + 53° = 180°
3x = 180° - 53°
3x = 127°
<em><u>divide</u></em><em><u> </u></em><em><u>b</u></em><em><u>o</u></em><em><u>t</u></em><em><u>h</u></em><em><u> </u></em><em><u>sides</u></em><em><u> </u></em><em><u>by</u></em><em><u> </u></em><em><u>3</u></em>
x = 42,33°
Neither is bigger than the other, because they're equal. 3/5 as a decimal is 0.6
