Answer: 2π ft^2
Step-by-step explanation:
Area of a circle= π x the radius ^2
here your diameter is 4, and the radius is equivalent to half of the diameter so your radius equals 2.
A= π x 2^2
The first one is c
(x+7)(5)
Distribute and multiply
5x +35
I don’t know about second one good luck
Answer:
1/3
Step-by-step explanation:
Answer:
area= 264.5 unit square
Step-by-step explanation:
let the width of the rectangle be x units then the length would be 2x units
perimeter = 2(l+b)= 2(2x+x)=2(3x)=6x
69=6x
x=69/6=11.5units
width is 11.5 units and length is 23 units
area= lxb= 11.5* 23= 264.5 units square
