Answer:
D
Step-by-step explanation:
They didn't provide the number for one of the faces btw..
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
Im pretty sure the answer is c) 136
Answer:
16 months
Step-by-step explanation:
40k-16.5k=23.5k. 23.5k/1450= A little bit more than 16 months.
Answer:
=
Step-by-step explanation:
The fractions are equal because we can simplify 3/6 to 1/3 as their biggest common divisor is 3
and
we can simplify 2/4 to 1/2 as their biggest common divisor is 2
So we are using the common divisor to simplify both fractions to solve this problem.
