Answer:
30
Step-by-step explanation:
15cm for 5
5 x 2=10
15 x 2 = 30
Area of circle = pi (d/2)^2
area of semi-circle =0.5* pi (d/2)^2
=0.5* pi (6/2)^2
=14.14
Answer:
x = 2.5 or -0.8
Step-by-step explanation:
Here, we are to use completing the square method to solve for the values of x
Firstly, we divide through by 4
= x^2 -7/4x -2 = 0
Now, we move the two term to the right hand side
x^2 -7/4x = 2
Now, we divide the coefficient of x by 2 and square it;
That would be;
(-7/4 * 1/2)^2 = 49/64
we now add this value to both sides of the equation
x^2 -7/4x + 49/64 = 2 + 49/64
The right hand side can be rewritten as;
(x-7/8)^2 = 177/64
taking the square root of both sides
x-7/8 = √(177/64)
x = 7/8 ± √(177/64)
x = 7/8 + √(177/74) or 7/8 - √(177/64)
= x = 2.53802 or -0.788017
Which to the nearest tenth is
x = 2.5 or -0.8
Answer:
The answer is
<h2>2√74 or 17.20 units</h2>
Step-by-step explanation:
The length of w line segment between two points can be found by using the formula

where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
S(-8, 7) and T (6,-3)
The length of ST is

We have the final answer as
<h3>2√74 or 17.20 units</h3>
