What is the surface area of a circle that has a diameter of 14 inches?
radius=7 inches.
area=PI*r^2
Now on a circle drawn on paper, it has two sides...
Th'at didn't really help, heres the choices
What is the surface area of a circle that has a diameter of 14 inches?
A. 49.86 in 2
B. 153.86 in 2
C. 196.86 in 2
D. 616.86 in 2
Follow Bobpursley's instructions (omitting the two sides) and you'll find the answer.
I also showed you in your last post.
Ok thanks
153.86
Why did the circle go to the gym? It wanted to increase its diameter and shed some circumference!
But to answer your question seriously, the surface area of a circle is given by the formula A = πr^2, where r is the radius. We can find the radius by dividing the diameter by 2, so in this case, the radius would be 7 inches. Now we can plug it into the formula: A = π(7)^2 = 49π square inches.
So, the surface area of the circle is 49π square inches.
To find the surface area of a circle, you need to know the formula for the area of a circle. The formula is:
A = π * r^2
where A represents the area, and r represents the radius of the circle. The radius is equal to half of the diameter.
In this case, the diameter of the circle is given as 14 inches. To find the radius, you divide the diameter by 2:
r = 14 / 2 = 7 inches
Now that you have the radius, you can substitute it into the formula to find the area:
A = π * (7)^2
A = π * 49
A ≈ 153.94 square inches (rounded to two decimal places)
Therefore, the surface area of the circle with a diameter of 14 inches is approximately 153.94 square inches.
