Pythagorean theorem is a^2 + b^2 = c^2. the hypotenuse is always the longest, so lets plug in the values.
a^2 + 12^2 = 20^2
if we simplify, we get a^2 + 144 = 400
then subtract 400-144 = 256
then find the sq. root of 256 = 16.
the answer is 16 feet
Answer: Area of shaded region is 1.72 ft²
Step-by-step explanation:
Area of shaded region = area of the rectangle - area of the semi circle.
The formula for determining the area of a circle is expressed as
Area = πr²
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
Since we are dealing with a semi circle, then
Area of semi circle = 1/2 × πr²
From the diagram,
Diameter = 4 ft
Radius = diameter/2 = 4/2
Radius = 2 ft
Area = 1/2 × 3.14 × 2² = 6.28 ft²
Considering the triangle,
Length = diameter = 4 ft
Width = radius = 2 ft
Area of rectangle = 4 × 2 = 8 ft²
Area of shaded region
= 8 - 6.28 = 1.72 ft²
The total meal including the tip cost for both girls together is $13.92
Explanation:
4.50 times 2 = 9
1.50 times 2 = 3
9 plus 3 = 12
16% of 12 = 1.92
12 plus 1.92 = 13.92
Answer:
It depends of what the equation is...
Step-by-step explanation:
If your equation is 3x2 (3x times 2) then the solution would be:
3(4)(2) + 5(2)= 34
If your equation is 3x + 2 + 5y, then the solution would be:
3(4) + 2 + 5(2) =24
That is 6 * sqrt(2*8*3*6)
= 6 sqrt 16 * sqrt 18
= 6 *4 * sqrt 9 * sqrt2
= 6*4*3 sqrt2
= 72 sqrt 2
