Radius of circle= 4
a) circle circumference=2(pi)r
circumference=2(pi)4=25.13
P=2W+2L
p=2(5)+2(10)
P=30
b) area of circle=pi(r^2)=pi(16)=50.27
area of rectangle=L×W= 5×10= 50
c) I think you can figure it put
The other ones will be 36, 108, 105, 315.
The answer is going to be the second one
Ed because 2 and 8 are equal
Answer:
45 square ft^2
Step-by-step explanation: The formula of the area of the trapezoid is A=(a+b)/2 x h. A represents the top while b represents the bottom. 15+3=18 and 18/2=9. If multiply the result by 5, you get 45 as the answer.
