The answer is to this is 14.
Given =
Two similar pyramid have base area of 12.2 cm² and 16 cm².
surface area of the larger pyramid = 56 cm²
find out the surface area of the smaller pyramid
To proof =
Let us assume that the surface area of the smaller pyramid be x.
as surface area of the larger pyramid is 56 cm²
Two similar pyramid have base area of 12.2 cm² and 16 cm².
by using ratio and proportion
we have
ratio of the base area of the pyramids : ratio of the surface area of the pyramids
x = 12.2 ×56×
by solvingthe above terms
we get
x =42.7cm²
Hence the surface area of the smaller pyramid be 42.7cm²
Hence proved
Answer: Maybe you could use a brainly tutor?
Step-by-step explanation:
Since ABC is a right triangle, we can use Pythagorean Theorem to solve for side AB.
Pythagorean Theorem: a^2 + b^2 = c^2
4^2 + 7^2 = c^2
16 + 49 = c^2
65 = c^2
c = 8.06

Answer:
7 and 1/2 tons
multiply the integer and fraction parts separately and then add them later.
Step-by-step explanation:
A simple way to find the total weight of the boxes mentally is to separate the integer part and the fraction part of the weight of each box. For the integer part, 3 boxes weighing 2 tons total 6 tons. For the fraction part, 3 boxes weighing half a ton total 1 and a half tons. Adding both parts gives a total of 7 and 1/2 tons.
