Answer:
21.46 cm²
Step-by-step explanation:
So we need to find the r for the circle
r=10/4=5/2
so the area of one circle is Ac=πr²
Ac=π(5/2)²=25/4π
and there are 4 of them: 25/4π*4=25π=78.54
the area of square is 10²=100
100-78.54=21.46 cm²
Find the perimeter of the yard ( the distance around the yard).
A rectangle has two sides of each dimension.
The perimeter is 20 + 20 + 45 + 45 = 130 feet.
Now multiply the total feet by the cost per foot:
130 feet x 25 per foot = $3,250 total.
Answer:
z = 52 degrees
Step-by-step explanation:
the angle adjacent to angle Z is 38 degrees because it is vertical and equal to the angle named as 38 degrees
i suppose these are squares, which have right angles (90°)
so, 90 - 38 = m ∠ Z
