IF YOUR SOLVING FOR A THE ANSWER WOULD BE A=X+12
IF YOUR SOLVING FOR X IT WOULD BE X=-12+A
Alrighty
we gots 1/4 circle and paralellogram
area circle=pi times radius^2
area paralelogram=base times height
1/4 circle is
radius is 10 so
area part circle is 1/4 times pi times 10^2=100/4pi=25pi=78.5 m²
area paralllogram is
10 times 3 because 3 is height and 10 is base length or 30
30+78.5=108.5 m² is the area
I don’t understand you second question but this is the work for the first one.
Hope it helps!
I think it is 8/17...
hope this helps!
