Find the area and the circumference of a circle with diameter 3 ft.

Zigmanuir [339]

Step-by-step explanation:

circumference of a circle

2×pi×r

area of a circle

pi×r²

r (radius) = diameter/2 = 1.5ft

we shall assume pi to be 3.14

circumference is

2×3.14×1.5 = 3.14×3 = 9.42 ft

area is

3.14 × 1.5² = 3.14×2.25 = 7.065 ft²

rjkz [21]

I'm not 100% sure but I think this is how you solve it:
1. 800,000 x 0.06 = 48,000
2. 48,000 x 17 = 816,000
3. 800,000 + 816,000 = 1,616,000
The painting is worth $1,616,000 in 2017.
