If the circumference of the circle is equal to 3.14 units, to find the area
The area of a circle can be calculated using the diameter or the radius with two different formulas: A = πr2 or A = π(d/2)2, where π is the mathematical constant approximately equal to 3.14,r is equal to the radius, and d is the diameter.
Answer:
78.5
Step-by-step explanation:
πr²
= π×5²
= 25π
= 78.5
The answer to this is A. 650. You find the surface area of the two cubes, then the rectangular prism, then you add them together.<span />
Answer:
x = 155
Step-by-step explanation:
First find the missing angle in the smaller triangle.
We know that the sum of the angles in a triangle is 180 so 35 + 90 + the missing angle = 180 so 180 - (35+90) = 180 - 125 = 55
Since the line above is a straight line, the sum of the angles must equal 180 so 55 + 60 + ? = 180. So 180 - 115 = 65.
The triangle is a right triangle so that means on of the angles is 90. So 65 + 90 = 155, so we have 180 - 155 = 25.
The angle that x is on is also a straight line so that means the angles must add up to 180 so 180 - 25 = 155.
