If m angle ECD is six less than five times m angle BCE, and mangle BCD = 162º. find each
Usimov [2.4K]

Answer:

see explanation

Step-by-step explanation:

let ∠BCE = x then ∠ECD = 5x - 6 and

∠BCE + ∠ECD = ∠BCD, substitute values

x + 5x - 6 = 162, that is

6x - 6 = 162 ( add 6 to both sides )

6x = 168 ( divide both sides by 6 )

x = 28

Hence

∠BCE = x = 28°

∠ECD = 5x - 6 = (5 × 28) - 6 = 140 - 6 = 134°

Find the volume of a hemisphere that has a diameter of 48 inches and leave your answer in terms of pie
marin [14]

<u>Given</u>:

Given that the diameter of the hemisphere is 48 inches.

We need to determine the volume of the hemisphere.

<u>Radius:</u>

The radius of the hemisphere can be determined using the formula,

r=\frac{d}{2}

Substituting d = 48, we get;

r=\frac{48}{2}

r=24

Thus, the radius of the hemisphere is 24 inches.

<u>Volume of the hemisphere:</u>

The volume of the hemisphere can be determined using the formula,

V=\frac{2}{3} \pi r^3

Substituting r = 24, we get;

V=\frac{2}{3} \pi (24)^3

V=\frac{2}{3} \pi (13824)

V=9216 \pi \ in^3

Thus, the volume of the hemisphere is 9216π cubic inches.
