Answer:
Hey mate here is your answer...
Step-by-step explanation:
smaller circular table to be made
with a diameter only half as big... and diameter of big table is (2*55)= 110cm.... So half diameter of big is (110/2)= 55cm
therefore, diameter of smaller table is 55cm and radius of it's (55/2)= 27.5cm
circumference of circle = 2πr
= 2*3.14*27.5
= 172.7 cm = 27.5cm
hope it helps you ❣️
Answer:
$4.72
Step-by-step explanation:
7.87÷5=1.574
1.574×3=4.722
so, $4.72 is your answer.
Well you already know your side lengths, so you use this formula S=1/2(A+B+C). For A put in one of your side lengths, for B put one of your side lengths, and for C put one of your side lengths. After you do that solve. But your not done. Once you find out what S equals by doing the formula I just showed you, you have to do another formula which is A= S(S-A)(S-B)(S-C). Once again plug in your side lengths for A,B, and C but then plug in your S value. (Remember you already found your S value by doing the first formula I showed you). Then do the math and then you will find your answer.
Answer:
Step-by-step explanation:
The midpoint of two coordinates (x1, y1) and (x2, y2) is expressed as;
M(X,Y) = {(x1+x2)/2, (y1+y2)/2}
Given the points A(h, k) and B(h,j)
x1 = h, y1 = k, x2 = h, y2 = j
Substitute into the formula;
M(X,Y) = {(x1+x2)/2, (y1+y2)/2}
M(X,Y) = {(h+h/2, (k+j)/2}
M(X,Y) = {(2h)/2, (k+j)/2}
M(X,Y) = {h, k+j/2}
hence the coordinates of point M is {h, k+j/2}
