Given: radius, "r", equal 7 in.
Given: height, "h", equals 4 in.
Volume: V = Base area * h ;
The base area of a cone is a circle: A = π * r² = π* (7²) = 49π .
(NOTE: Since all answer choices given are in terms of "π" ; we will leave the units in terms of "π").
V = (Based area) * h = (49π in.) * (4 in.) = (49*4)π in.³
= 196π in.³ ; which is: Answer choice: [D] .

Answer:
the blank number is 23
Step-by-step explanation:
8, 15, 27, x, 20
common ratio, r= T2÷ T1= T3÷ T2
= 15 ÷ 8 =27÷ 15
= 1.8 = 1.8
20 ÷ x = x ÷ 27
( cross multiply,)
x²= 540
x =√540
x = 23.24
x = 23
The answer is x = 4 as it satisfies both inequalities :)
Prime= 19, 37, and 47
Composite= 9, 15, 26, 33, and 45
Hope this helps!
The probability that both cards are kings is 4/52 times 3/51. This is 12/6256, or 1/221.
