Step-by-step explanation:
π= 3.14
Given
Circumference = 12.56 units
First calculating radius
so 2πr = 12.56
2 * 3.14 * r = 12.56
6.28 r = 12.56
Therefore r = 2 units
Now calculating Area
Area = πr²
= 3.14 * 2²
= 12.56 square units

Answer:
x = 25 B = 65˙ C = 50˙
Step-by-step explanation:
Triangle Sum- All three angles in a triangle add up to 180˙
65 + (3x - 10) + (2x) = 180
65 - 10 +3x + 2x = 180 Combine like terms
55 + 5x = 180 Move the 55 over to combine w/180.
<u>- 55 -55 </u>
<u>5x</u> = <u>125</u> Divide by 5
5 5
x = 25 Answer
B C
(3x - 10) (2x)
(3*25 - 10) (2* 25)
65˙ 50˙
Answer:
what is the question asked?
Step-by-step explanation:
No because solids can't transmit heat by convection, and convection only works because of hotter and quicker moving molecules have a lower density so they rise to the surface. But in a solid, the molecules can't move relative to each other. They only vibrate :)
