Divide both sides by 25 to isolate x:
The area would be 83.67 cm.
A semicircle is half of a circle. The perimeter of the semicircle would be half of the perimeter (circumference) of the entire circle. The formula for circumference is:
C=πd
Using our information, we have
22.92 = 0.5(3.14)d
22.92 = 1.57d
Divide both sides by 1.57:
22.92/1.57 = 1.57d/1.57
14.6≈d
Since the diameter is 14.6, the radius is 14.6/2 = 7.3.
We use the radius for the area of the semicircle:
A=0.5πr²
=0.5(3.14)(7.3)²
=83.67
Answer: 1
Step-by-step explanation:
8 yellow / 8 total = 8/8 = 1
The formula is d=C/π.
The diameter is 2 times the radius
The formula for the circumference using the radius is 2πr.
in order to do this backwards, we would have to do 16÷2÷π, but we're not looking for the radius.
Therefore, we take out the ÷2 part, which would be 16÷π
16 is the circumference
16÷π=d
d=C÷π
Answer:
D) (10,22)
Step-by-step explanation:
based on given slope and point, the linear equation is <em>y = 9/5x + 2</em>
plugging in x-and-y values only results in a true statement for option D
example:
22 = 9/5(10) + 2
Does 22 = 18 + 2? Yes
