The area of a full circle would be Area = PI x r^2
The diameter would be the width of the dorr, so the radius would be half that. 34/2 = 17 inches.
Area for a full circle would be 3.14 x 17^2 = 907.46 square inches.
A semi circle is a half circle.
The area would be 907.46 / 2 = 453.73 square inches.
Multiply the area by the cost:
453.73 x 0.95 = 431.04
The answer is C.
Answer:
slope=4root5
Step-by-step explanation:
H^2=b^2+ h^2
(8)^ +(4)^
= 64+16
H^ =80
H= ROOT 80
root(4*4*5)
=4root(5)

multipy 10 to both terms
50 20x
subtract products
50 - 20x
Answer:
Step-by-step explanation:
You have a right triangle here. The way to solve for a missing side in a right triangle is to use Pythagorean's Theorem. You can't use right triangle trig because you don't have an angle. Pythagorean's Theorem is, in this case,
and
and
so
which simplifies down to
