Answer:
3311.36ft^3
Step-by-step explanation:
Given data
Height h= 11.9ft
Radius=16.3ft
The expression for the volume of a cone is given as
Volume= 1/3πr^2h
substitute
Volume=1/3*3.142*16.3^2*11.9
Volume= 1/3*3.142*265.69*11.9
Volume= 1/3*9934.095962
Volume=3311.36ft^3
Hence the volume is 3311.36ft^3
Answer:
28 units²
Step-by-step explanation:
Assume that your net has the dimensions shown below.
Its area is
2 yellow rectangles = 2(4 × 2) = 2 × 8 = 16 units²
2 grey rectangles = 2(4 × 1) = 2 × 4 = 8 units²
2 green rectangles = 2(2 × 1) = 2 × 2 = <u> 4 units²</u>
TOTAL = 28 units²
The prism's surface area is 28 units².

Answer:
probability of lasting longer = 1.7%
Step-by-step explanation:
We are given:
x' = 14 years
μ = 12.3 years
s = 0.8 years
Thus, let's use the formula for the Z-score value which is;
z = (x' - μ)/s
Thus;
z = (14 - 12.3)/0.8
z = 2.125
From the z-distribution table attached, the p-value is ;
P(x' > 2.125) = 1 - 0.983 = 0.017 = 1.7%
Thus,probability of lasting longer = 1.7%
