Answer:
4524.9
Step-by-step explanation:
<u>Area of a parallelogram:</u>
A = bh
A = 63 x 90
A = 5670
<u>Area of half-circle:</u>
A = (πr²)/2
A = (π x 27²)/2
A = (π x 729)/2
A = 729/2π
<u>Combined:</u>
5670 - 729/2π
4524.9
Y=x-5
6=x-5
6+5=x-5+5
11=x
x=11
Answer:
The perimeter of a circle is π × d. Here's is the diameter of the circle. Hence, the perimeter of a circle is half of that of the circle that is ½ π × d.
The area of a circle is pi times the radius squared (A = π r²). Learn how to use this formula to find the area of a circle when given the diameter.
