Step-by-step explanation:
Srectangle=21*30=630cm^2
Ssemicircle=(11.5^2*pi)/2=132.25pi/2=66.125cm^2*pi
Sfigure=630cm*2+2*66.125cm^2*pi=630cm^2+pi*132.25pi
if we assume that pi=3.14
Sfigure=630cm^2+415.265cm^2=1045.265cm^2
Answer:
<6 = 68
Step-by-step explanation:
<5 + <6 + 90 = 180 since the 3 angles form a straight line
22 + <6 + 90 =180
Combine like terms
112+ <6 = 180
Subtract 112 from each side
<6 = 180-112
<6 =68
