What is the difference between the areas of a circular table with diameter 6 ft and a circular table with diameter 8 ft? round your answer to the nearest square foot. a) 18 ft squared b) 22 ft squared c)16 ft squares d) 20 ft squared

If the diameter is given in a problem, area is computed as

A = (π/4) × D2   where π is equal to 3.14

If D (diameter)  of one circular table is 6 ft its  Area is 28 sq ft.

If D of another circular is 8 ft its Area is 50 sq ft.

The difference between the areas of the two tables is, therefore (50-28) or 22 sq. ft.

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
