-pi. this one was asked very recently
- Circumference = 6cm
- Let the radius be r.
- Therefore, 2πr = 6 cm
- Given, height = 8 cm.
- Therefore, curved surface area of the cylinder = 2πrh
- = (6 × 8) cm^2
- = 48 cm^2
<u>Answer</u><u>:</u>
<u>4</u><u>8</u><u> </u><u>cm^</u><u>2</u>
Hope you could understand.
If you have any query, feel free to ask.
X=-5.5 the other zero would be x=-0.5 but that’s not an option.
Answer: x=3 and y=5
Step-by-step explanation: 11x-6y=3, 5x-8y=-25
11x-6y+6y=3+6y
11x/11=3/11+6y/11
x=3+6y/11
5(3+6y/11)-8y(11)/11
5(6y+3)-88y/11
30y+15-88y/11
88y-30y
58y
11(15-58y)/11=11(-25)
15-58y-15=-275-15
-58y/-58=-290/-58
y=5
x=3+6(5)/11
3+30
33
33/11
x=3
x=3, y=5
The measure of the central angle is 4 radians
<h3><u>
Solution:</u></h3>
Given that central angle of a circle intercepts an arc of length 28 centimeters
The radius of the circle is 7 centimeters
<em><u>To find: measure of the central angle in radians</u></em>
The arc length of circle when 
is measured in radians is given as:
Where "s" is the arc length
"r" is the radius of circle
is the central angle in radians
Substituting the values in formula,
Thus the measure of the central angle is 4 radians
