Answer:

60.6

Step-by-step explanation:

The rectangle is 12*4. You have the radius of the semicircle, so you multiply that by 2 to get 4 for the diameter, then getting the width of the rectangle.

After that, do pi * r^2. This will be pi*4. You'll get 12.6.

After multiplying 12*4, 48, you add 12.6 and 48, and get 60.6

The length of the hypotenuse of a right triangle is one unit more than twice the height. What is the height of the triangle if t
lisabon 2012 [21]

The height of the triangle if the base is 8 is 3.96 units

Given the following parameters

Base of a triangle = 8 units

Let the hypotenuse be "c"

Let the height be "h"

If the length of the hypotenuse of a right triangle is one unit more than twice the height, then;

c = 2h + 1

According to the Pythagoras theorem:

c² = b² + h²

(2h + 1)² = 8² + h²

Expand

4h²+4h+1 = 64 + h²

4h²-h² + 4h + 1 - 64 = 0

3h² + 4h - 63 = 0

Factorize the result

On factorizing, the value of the height is 2

h = \frac{-2}{3}+\frac{\sqrt{193} }3\\

h = 11.89/3

h = 3.96 units

Hence the height of the triangle if the base is 8 is 3.96 units

the product of five consecutive odd integers is 945 what is the greatest possible value of any of these integers
Troyanec [42]
If 945 is the product of 5 CONSECUTIVE ODD  numbers, let's find the prime factors of 945:

945 = 5 x 7 x 27 , but we need 5 odd numbers:

945= 5 x 7 x ( 3 x 9 ) we still need one factor. This factor cannot be but 1

945 = 1 x 3 x 5 x 7 x 9 = 945 and the greatest value of these integers is 9
