Circumference =2*pi*r
Therefore 3*6.87*3.14
=64.7154ft
is the answer.
by rounding 70ft
Answer:
QR = 19.4
Step-by-step explanation:
Use Pythagoras because p = 90°
Qr is hypotenuse
; (15.5)² + (11.7)²
= 377.14
√377.14
= 19.42009
= 19.42
= 19.4

Answer:
The area of the triangle is: "
8.5 cm² " ;
or, write as: "
8
cm² " .
_______________________________________________________Explanation:_________________________________________________________The formula {"equation"} for the area of a triangle is:
A = (

) * b * h ;
in which: A = area;
b = base;
h = [perpendicular] height;
___________________________________{also, can be written as: " A = (b * h) / 2 " .}.
______________________________________Solve for the area, "A" ; by plugging in the known values shown in the figure (image attached):
______________________________________
base, "b" = 13 cm ;
[perpendicular] height, "h" = 5 cm ;
______________________________________A = (b * h) / 2 ;
= (13 cm * 5 cm) / 2 ;
= [ (13 * 5) cm²] / 2 ;
= 65 cm² / 2 ;
A = "
8.5 cm² " ; or, write as: "
8
cm² " .

Answer: C
Explanation:
1/3(6+3i) - 2/3(6 - 12i)
= 2 + i - 4 + 8i
= -2 + 9i
Okay so the equation you need to use is (x2/a2)+(y2/b2)-(z2/c2)=1
So an equation describing the shape of the tower
in the coordinates where the origin is at the center of the narrowest part of
the tower would be:
<span>x^2 / 100^2 + y^2 /
100^2 – z^2 / 2 * 100^2 = 1</span>
