Step-by-step explanation:
Diameter =12 ft
i.e 2r=12
or, r=12/2 =6ft
SA =3πr²
=3(6)²π ft²
=3×36π ft²
=108π ft²
Answer:
have four sides with two pairs of sides that are parallel.
Step-by-step explanation:
Let s be the side of the square. The length of the rectangle is 3s and its width is equal to s - 2. From the given condition,
A (square) = A (rectangle)
s² = (3s)(s - 2)
s² = 3s² - 6s
-2s² = -6s
s = 3
Thus, the length of the rectangle is 9 and its width is 1
3:40
1:13
it would be 13.3 repeated but since you round to the nearest dollar it would be 13. All I did was divide 40 by 3.
