Answer:

21.74 ft

Step-by-step explanation:

We use Cosine because we are dealing with the Adj and Hyp

Cos 85 = x/20

x = 20 Cos 85

x = 1.74 feet away from the base of the wall.

Since the ladder is 20 foot long, the total distance will be 1.74 + 20 = 21.74 ft

Answer:

25.133 units

Step-by-step explanation:

Since the density ρ = r, our mass is

m =  ∫∫∫r³sinθdΦdrdθ. We integrate from θ = 0 to π (since it is a hemisphere), Φ = 0 to 2π and r = 0 to 2  and  the maximum values of r = 2 in those directions. So

m =∫∫[∫r³sinθdΦ]drdθ      

m = ∫[∫2πr³sinθdθ]dr     ∫dФ = 2π

m = ∫2πr³∫sinθdθ]dr

m = 2π∫r³dr    ∫sinθdθ = 1

m = 2π × 4     ∫r³dr = 4

m = 8π units

m = 25.133 units
