Answer:
The diameter of the circle would be: 6.4 cm. rounded or 6.36619772 cm.
The radius of the circle would be: 3.2 cm. rounded or 3.18309886 cm.
Step-by-step explanation:
<h3>The diameter can be solved using: D =
</h3>
So, the first step would be : D =
Then : D = 20 ÷
Finally, the answer will be : 6.36619772 cm. or 6.4 cm.
<h3>The Radius can be Solved using: r =
</h3>
The first step would be : r =
Then : 20 ÷ 6.2831853071796 (2)
Finally, the answer will be : 3.18309886 cm. or 3.2 cm.
Answer:
3(2c+d)−d
Distribute:
=(3)(2c)+(3)(d)+−d
=6c+3d+−d
Combine Like Terms:
=6c+3d+−d
=(6c)+(3d+−d)
=6c+2d
=6c+2d

Answer:
2√46 + 25π/4 ≈ 33.2 . . . . m²
Step-by-step explanation:
The altitude of the triangle is given by the Pythagorean theorem. The right triangle of interest is the one that has 5√2 as its hypotenuse, and a leg of half the base shown. Then the other leg, the altitude of the triangle, is ...
h = √((5√2)² - 2²) = √46
Then the area of the triangle shown is ...
A = (1/2)bh = (1/2)(4)(√46)
A = 2√46
__
The area of the semicircle is given by the formula ...
A = (1/2)πr²
Filling in the radius shown, the area is computed as ...
A = (1/2)π(5√2/2)² = 25π/4
So, the total area of the figure is ...
total area = triangle area + semicircle area
= 2√46 + 25π/4 . . . square meters
≈ 33.2 . . . square meters
