Answer:
Step-by-step explanation:
P = 2(L + W)
P = 56
L = 12
now sub...we are looking for w
56 = 2(12 + W)
56 = 24 + 2W
56 - 24 = 2W
32 = 2W
32/2 = W
16 = W <==== the width is 16 inches
check...
P = 2(L + W)
56 = 2(12 + 16)
56 = 2(28)
56 = 56 (correct)

Answer:
56.52 in
Step-by-step explanation:
Circumference Formula: C = 2πr
Since we are given radius <em>r</em> = 9, simply plug it into the formula:
C = 2π(9)
C = 18π
C = 56.5487
The weight of the spherical sculpture in pounds is approximately 251607 pounds
<h3>How to find the weight of the sculpture in pounds?</h3>
The sculpture is spherical and its made of solid bronze.
Therefore,
density = mass / volume
where
density = 7700 kg / m³
volume = 4 / 3πr³
volume = 4/ 3 × 3.14 × 1.524³
volume = 44.4574491494 / 3
volume = 14.8191497165 m³
Therefore,
mass = 7700 × 14.8191497165
mass = 114107.452817 kg
1 kg = 2.205 pounds
114107.452817 = ?
cross multiply
mass in pounds = 114107.452817 × 2.205
mass in pounds = 251606.933461
mass in pounds = 251607 pounds
