Answer:
499.2
cm²
Step-by-step explanation:
See attachment for the figure.
The area of a triangle is given by
A = 1/2bh
A = 1/2(12)(10.4)
A = 62.4
cm²
Then, take that area and multiply it by the number of faces. In this problem, there are 8.
62.4 × 8 = 499.2
cm²
The area of a circle of diameter d is given by
.. A = (π/4)d^2
so the area of a semicircle with that diameter will be half that.
The banner has area
.. (26 in)^2*(1 +π/8) ≈ 941.33 in^2
Answer:
value of x = -4
Step-by-step explanation:
here's the solution : -
=》3x - 4 = 2x - 8
=》3x - 2x = -8 + 4
=》x = -4
