Area of each lateral area = 1/2 * 14* 15
Total lateral area ( as it has 3 lateral sides) = 3 * 1/2 * 14 * 15 = 315 cm^2
Total surface area = 315 * 1/2 * 14 * 15 = 420 cm^2
Hexagonal pyramid
Lateral area = 6 * area of each triangle = 6 * 1/2 *10 * 35 = 1050 cm^2
Total S A = 1050 + area of the hexagonal base = 1050 + 3 sqrt3 10^2 / 2
= 1050 + 259.8 = 1309.8 cm^2
R u sure this is a college question.... well do 8 x 91 to get the numerator then 10 x 1 to get the denominator e.g ( x/y ) then simplify
f - 23 = 23
Add 23 to each side: f = 46
Explanation:
You need to use the unit circle. Once you have one pulled up, find the angles for which the cosine equals Pi/4.
Brainliest would be appreciated. :)
