Answer:
B. 88.5
Step-by-step explanation:
first we add all the numbers :
(79 +80 +92 +92 +81 +100 +88 +98 +71 + 100+91+90) over 12
= 1062 over 12
= 88.5
[why over 12? because there's 12 numbers]
Radius = 6 inches
Arc lenght = 11pi inches
Degrees ?
Arc lenght = radius x angle in radians
A = r * a
Solving for a:
a = A/r = 11pi/6 = 5.759586532 radians
5.759586532 to degrees ==> a = 330 degrees
Answer:
330 degrees
The answer is 8, because CA and BC are equal
The answer is 85%.
If you're solving without a calculator, you can simply multiply the numerator and denominator so that the denominator is equal to 100. So, for this fraction, you would multiply both the top and the bottom by 5.
17/20
17(5) / 20(5)
85 / 100
85%
132 in
Step-by-step explanation:
- Take the total radius = 18+3 = 21= R (say)
- Simply use the formula for the circumference i.e. 2*pi*R
- 2*22/7*21= 132
