Answer:
A = 1/2bh
b = 2cm
h will be found using the side of the triangle with Pythagoras theorem
h² + 1² = 4²
h² = 15
h = √15 cm
then,
A = <u>2</u><u>*</u><u>√</u><u>1</u><u>5</u><u> </u>
2
A = √15cm²
1188 = π<em>r</em>²<em>h</em>
For the formula to solve for <em>h, </em>you have to change the equation to:
<em>h </em>= 1188/π<em>r</em>²
which is just moving h to the left side of the equation, and moving v(in this case 1188) to the right side.
because <em>h </em>was multiplied to the original equation, switching sides in an equation makes its replacement(1188) into a devision. (if you move a number across the = sign, the number will become the opposite of itself.)
Since you don't know the radius, you can't simplify this equation.
The answer is <em>h </em>= 1188/π<em>r</em>²
The probability of not getting a number greater 5, when rolling a die is 1 out of 6
Answer:
1/6.
Step-by-step explanation:
x / 4/7 = 7/24 where x is the dividend.
7x/4 = 7/24
Cross multiply:
7x * 24 = 4*7
x = 28/(7*24)
= 28/168
= 1/6.
