Answer:
26π
Step-by-step explanation:
26π because the formula is πd=circumference
The area of the rectangular garden is 50 x 10 = 500 square feet.
The perimeter of the rectangular garden is 50 + 50 + 10 +10 =120 feet.
The perimeter of the square also needs to be 120 because it is using the same amount of fence.
Divide 120 by 4 sides: 120/4 = 30
Each side of the square garden would need to be 30 feet.
The area of a square is Side^2, 30^2 = 900 square feet.
The square is 900 - 500 = 400 square feet more.
Answer:
The area of the circle with a radius of 5 cm is 78.5
π·5^2=78.5
Answer:
k = 77
Step-by-step explanation:
k ÷ 11 = 7
We can reverse the equation to 7 x 11 =k
Using the multiplication tables, we know that 7 x 11 is 77
Therefore:
k = 77
Plug it in:
77 ÷ 11 = 7
