I'm having problems with this question, to tell you the truth I don't understand the problem.
Andrew is considering building a clubhouse in the shape of a rectangle. His sketch of the clubhouse is.... (its a drawing of a rectangle with 8 ft at the top and 4 ft on the left end)What would the area of the clobhouse be? I answer 24 ft.
The next question asked ....
on one wall of the clubhouse,Andrwe wants to cut a large circular opening to be a window. The circle radiusis 2 ft. What will the circle circumference be? (This is what i don't understand) Please help me!!
cirsumference of a circle equals 2*pie*radius
If the clubhouse is 8 feet by 4 feet, the area wouldn't be 24 feet.
8 * 4 = ?? sq. feet
To find the circumference, multiply Pi times the diameter.
C = 3.14 * 4
C = ??
by multiplying 8 by 4 is 32ft?
C = 1256
if this is the right answer, I still confused, please help me understand
Yes. The area of the clubhouse is 32 square feet.
But you're way off on the circumference. Where does the decimal point go?
C= 12.56
Right. The circumference of the circle is 12.56 feet.
To find the circumference of a circle, you need to use the formula:
C = 2πr
where C represents the circumference, π is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.
In this case, the radius of the circular window is given as 2 ft. Therefore, you can substitute the value of the radius into the formula:
C = 2π(2)
C = 4π
So the circumference of the circular window would be 4π ft. This is the exact value of the circumference. However, if you need to provide an approximate value, you can use 3.14 as a decimal approximation for π:
C ≈ 4(3.14)
C ≈ 12.56 ft
Therefore, the approximate circumference of the circular window would be 12.56 ft.
