The left side is a half circle.
The area of a circle is PI x r^2
The diameter of the circle would be the height of the rectangle, given as 10 feet.
The radius is 1/2 the diameter, so 5 feet.
The area of half the circle is (3.14 x 5^2) / 2 = 39.25 square feet.
The area of the rectangle is 20 x 10 = 200 square feet.
Total area = 200 + 39.25 = 239.25 square feet.
= [3x3^-2x(-2)^6/2x3^-1x(-2)^5]^2 = 1
Answer:
3 1/3π
Step-by-step explanation:
First, you have to find the circumference. The circumference, based on the equation of 2rπ, comes out as 20π. Since you have to find the length of the arc that is 60 degrees, divide 60 by 360 to see how much of the circle 60 degrees is. It results in 1/6, so then you simply have to multiply 20π by 1/6.
Answer:
V = 672 cm³ (Option 3)
Step-by-step explanation:
Volume of Rectangular Prism = 
<u><em>Where L = 14 cm, W = 6 cm and H = 8 cm</em></u>
V = 14 * 6 * 8
V = 672 cm³
Answer:
The correct answer is H
Step-by-step explanation:
1/4 of a wall in 2/3 of an hour is 40 min
so a wall takes 160 min which is 2 hours and 40 min
so 3 walls takes 8 hours
