Answer:
130 ft²
Step-by-step explanation:
Step-by-step explanation:
we know ,
area of circle =πr^2
hence we get from the figure that the diameter of circle is 19 cm and we can find radius
r=d/2
r=18/2=9cm
area of semicircle =πr^2/2
area of Semi circle equals to =22*(9)^2/7/2
=127.2857143

Answer:
x=4/7
Step-by-step explanation:
You can write 36^4x-1=6^x+2 to 6^2(4x-1)=6^x+2. Then you can write
2(4x-1)=x+2, 8x-2=x+2, 7x=4, x=4/7
