Answer:

P = 42 cm

Step-by-step explanation:

The perimeter (P) is the sum of the 4 sides of the rectangle with opposite sides being congruent.

Given width = 7 cm then length = 2 × 7 = 14

P = 7 + 7 + 14 + 14 = 42 cm

Answer:

Volume, $V=3052.08\ ft^3$

Step-by-step explanation:

It is given that,

Diameter of spherical boulder is 18 ft

Weight of spherical boulder is 8 tons.

We need to find the volume of spherical boulder. The formula of the volume of sphere is given by :

$V=\dfrac{4}{3}\pi r^3$

r is radius of spherical boulder, r = 9 ft

Substituting all values in above formula :

$V=\dfrac{4}{3}\times 3.14\times (9)^3\\\\V=3052.08\ ft^3$

The volume of spherical boulder is $3052.08\ ft^3$ .
