What is the circumference of a circle with a diameter of 70 yd? Round your answer to the nearest yard.
A. 220 yd
B. 1,540 yd
C. 210 yd
D. 440 yd
C = d π
C = 70 π = 70 ∙ 3.141592654 = 219.91148578 yd
C = 220 yd
rounded to the nearest yard
just multiply 70 mm with pi (3.14) which gives you 219.8 but it said to round to the nearest yard which is 220 so your answer is 220 Yard

To find the circumference of a circle, you can use the formula:
C = πd,
where C is the circumference and d is the diameter of the circle.
In this case, the given diameter is 70 yd. So, we can substitute this value into the formula:
C = π * 70.
Now, to find the circumference rounded to the nearest yard, we need to find the value of π. The value of π is approximately 3.14159.
So, we have:
C = 3.14159 * 70.
Calculating this, we find that C ≈ 219.98. Rounding to the nearest yard, the circumference is approximately 220 yd.
Therefore, the correct answer is A. 220 yd.
