Question

The Astrodome in Houston, Texas, is circular and has a diameter
of 710 feet. What is the approximate circumference of the Astrodome?​

Answer 1

Answer:

$d = 710 \: feet \\ r = d \div 2 \\ r = 710 \div 2 \\ r = 355 \: feet \\ circumference = 2\pi \: r \\ = 2 \times 3.14 \times 355 \\ = 2229.4 \\ = 2229 \: feet(approx.)$

step by step solution

Answer 2

Answer:

2230 ft

Step-by-step explanation:

Diameter = 2×radius

710 ft = 2×R

R = 355 ft

Now, we know the circumference formula that is (2 pi R)

[ pi = 22/7 or 3.14 ]

So.. lets calculate it

2 × 22/7 × 355

710× 3.14

71 × 31.4

2229.4 ..

that is almost 2230 feet.
