What is the best approximation for the area of this circle?

Use 3.14 to approximate pi.

Circle with radius labeled 6 ft

18.8 ft²

37.7 ft²

75.4 ft²

113.0 ft²

. Correct option is D) 113.0 ft² .

Step-by-step explanation:

Here we have , A circle labeled with radius = 6 ft . We need to find the best approximation for the area of this circle . Let's find out:

We know that area of circle = , We have following parameters as

So , Area of circle is

⇒

⇒

⇒

⇒

On Rounding off

⇒

Therefore , . Correct option is D) 113.0 ft² .

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
