That means 2*3* the sum of 5+8 which gives you 78 as your answer. Hope this helps and please select as the brainliest answer.
The radius of the circle is 15 cm,
The diameter of the circle is 30 cm,
The circumference of the circle is 94.248 cm,
The area of the circle is 706.86 cm^2
The radius is given in the diagram as half the circle, which is 15 cm.
The diameter is double the radius because the diameter measures the circle from edge to edge, so 15•2=30 cm.
The circumference of the circle is 2•3.14•r=C,
2•3.14=6.28, 6.28•15= 94.248 cm.
The area of the circle is 3.14•r^2, so the radius squared is 225 (15•15) and 225•3.14=706.86 cm squared :)
P=2L+2W
380=2*70+2W
380=140+2W
2W=240
W=120
The dimensions are 70 yd and 120 yd
Hope this helps!
The answer will be A
Step by Step Calculation
Length = √((x2 - x1)2 + (y2 - y1)2)
= √((-8-(4))2 + (7-(2))2)
= √(144+25)
= √(169)
= 13
The denominator 13 cannot be factored so that only 2's and 5's show up, so this means that 2/13 is a non-terminating decimal. Therefore, this decimal repeats itself
Use a calculator to see that: 2/13 = 0.153846 153846 153846 ....
The spaces are put in to help make the number more readable. Note how the "153846" keeps repeating forever
