The answer is B
1cm = 100km
d cm= 135km
d= (135x1)/100
d= 135/100
d= 1.35
Answer:
Therefore, the centre of the circle is in <u>( -2, 1 )</u>
and the radius of the circle is 2.
<u>Formu</u><u>la</u><u> used</u><u> </u><u>:</u><u>-</u><u>-</u><u>-</u><u>-</u><u>-</u>
equation of the circle
where r is the radius of the circle.
<h2>(A) 2 is the right answer.</h2>
Whats the rest of the question
1 yard = 3 feet
The foundation is 2/3 yard wide, by 1 yard deep by 10 yards long.
Volume is Length x width x height.
Volume = 2/3 x 1 x 10 = 6.66 cubic yards.
The answer is B.
surface area: 314
formula: A = 4pi r^2
volume: 523.33
formula: V = 4/3pi r^3
to solve you’d just plug in your radius (r), which in this case it’s 5
