Answer:
11
Step-by-step explanation:
6^2 = 6 x 6 = 36
5^2 = 5 x 5 = 25
36 - 25 = 11
Answer:
Step-by-step explanation:
(1). A = π r²
A = 4 π
Area of shaded region is 
= 
or 
(2). C = 4 π
In this case, the length of the bigger arc and the area of shaded region happen to be the same.
The length of the arc ADB is or
A because, all the numbers multiplied by those factors equals their spot in the number
To solve this problem, we have to find the perimeter of the shape.
we already know that two of the sides are 82m, all we need to do is find the circumference of the semicircles.
to find circumference, you multiply the diameter of a circle by pi. since we have two identical semicircles, we have one full circle. 66•3.14=207.24
207.24+82+82=371.24
the answer is 371.24m
