Answer:
3.5 cm
Step-by-step explanation:
Given the question:
A circular arc has measure 8 cm and is intercepted by a central angle of 2.3 radians. Find the radius of the circle. Do not round any intermediate computations, and round your answer to the nearest tenth.
Central angle in radian (θ) = 2.3 radian
Length of arc (s) = 8cm
Recall:
Length of arc (s) = radius (r) × central angle (θ)
8cm = radius × 2.3 rad
radius = 8 / 2.3
Radius = 3.478 cm
Radius = 3.5 cm
Area = length x width
Area = 1.25 x 3.4 = 4.25 square meters
An example should make this clear.
If $50 is 40% what is the value of the whole amount?
Answer:- Whole amount = 100^%
By proportion this = (100/ 40) * 50
= 2.5 * 50
= $125 (answer)
Answer:
5x19=95
Step-by-step explanation:
The Prime Factors and Pair Factors of 95 are 5 × 19 and (1, 95), (5, 19) respectively.
All Factors of 95: 1, 5, 19 and 95.
Negative Factors of 95: -1, -5, -19 and -95.
Prime Factors of 95: 5, 19.
Prime Factorization of 95: 51 × 191
Sum of Factors of 95: 120.
In all you have 54 buttons because if you add 10 plus 10 that equals 20 plus 34 and that gets 54 buttons in all
