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 $3052.08\ ft^3$ .

1. One face is 5.1*2.5=12.75 un^2, one is 8.5*2.5=21.25, one is 6.8*2.5=17, and two are 1/2*6.8*5.1, so both are 34.68. Total is 85.68, rounded to 85.7 cm^2. (C)

2. The area of the circles is 2(π*2^2), which is about 25.1. The rectangle's area can be found as 2π*2*3, which is about 37.7. The total is rounded to 62.8 m^2 (D)

3. Rectangular faces: 3.6*1.8=6.48, 8.5*1.8=15.3, 7.7*1.8=13.86

Triangles: 2(1/2(3.6*7.7))=27.72

Total: 63.36, round to 63.4 km^2 (B)
