Answer:
1.5
Step-by-step explanation:
we calculate the circumference of this circle.
circumference of a circle=2πr
data:
r=8 mm
circumference=2(8 mm)π=16π mm
2)we calculate the measure, in radians of the angle.
We know that:
circumference of a circle=2π radians
therefore:
16π mm=2π radians.
16 π mm--------------------------2π radians
12 mm----------------------------- x
x=(12 mm * 2π radians) / 16π mm=1.5 radians.
Answer: d) 12 ft
Step-by-step explanation:
Let x be the width of the room , the the length of the room will be 2x.
We consider the shape of room is rectangle.
We know that the area of rectangle is given by :-
, where l is length and w is width.
Given : Area of the room is 288 square feet
Since, width cannot be negative, so the width of the room = 12 feet.
<span>S= (a+b)^2+(4a+b-2)^2+(9a+b-4)^2
98a+14b-44=0
14a+3b-6=0
a=24/49, b=-2/7
y = (24/49)x^2-(2/7)</span>
According to the given data we have the following:
what does 68.47 + 75.20 + 60.05 equal to
So, in order to calculate this, first we would sum the decimals of this numbers as follows:
0.47+0.20+0.05=0.72
Then procees to sum the numbers 68+75+60
So, 68+75+60=203
Therefore, 203+0.72=203.72
So, 68.47 + 75.20 + 60.05 equal to 203.72
