Find the surface area of the figure. Round to the nearest hundredth when necessary.

Solution given;

slant height[l]=32km

side of equilateral triangle (a)=14km

now

total surface area of triangular pyramid =

area of base triangle +3 area of traingular faces

=√3/4 a²+3×½×{b×l}

=√3/4 14²+3/2×{14×32}

=756.87=757 km² is a required surface area.

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%

answer: 0.26
