Answer:
Because triangle has three sides
Hey there! :)
Answer:
V = 3408 units³
Step-by-step explanation:
Given:
r = 12
h = 71
Volume of a cone: V = 1/3 (bh) where b = πr²
Calculate the area of the base:
A = 12²π
A = 144π units²
Plug this into the formula for the volume of a cone:
V = 1/3 (144π · 71)
V = 1/3 (10224)
V = 3408 units³
18.84 because circumference is 2piR so 2(3)(3.14)= 18.84
Answer:
Step-by-step explanation:
remember that a trapezoid is a quadrilateral with one pair of parallel. sides the formula for the area of a trapezoid is area. equals one-half times parentheses base one plus base two times. height where the bases are the parallel sides
Answer:
After completing the square the expression is (x-2)^2 -12 =0 and real solution are x = 5.46 and x = -1.46
Step-by-step explanation:
We need to complete the square:
x^2 − 4x − 8 = 0
x^2 -2(x)(2)+(2)^2 -8 -4 =0
(x^2 -4x +4) - 12 = 0
(x-2)^2 -12 =0
Now, finding the value of x
(x-2)^2 -12 =0
(x-2)^2 = 12
taking square root on both sides
So, After completing the square the expression is (x-2)^2 -12 =0 and real solution are x = 5.46 and x = -1.46
