Answer:
A = 31.4 inches^2 to the nearest tenth of a square inch
Step-by-step explanation:
In this question, we are asked to calculate the area of the sector of a circle given the value of the radius and the angle subtended at the centre.
To calculate this, we employ a mathematical approach.
The area of the sector of a circle can be calculated as follows
A = ϴ/360 * π * r^2
Where ϴ is the angle subtended which is 100 and r is the radius.
Thus, we have
A = 100/360 * 22/7 * 6 * 6
A = 31.428 inches^2
To the nearest tenth of a square inch, A = 31.4 inches^2
Answer:
Step-by-step explanation: If you meant f(x)=x^2, the domain would be (-∞,∞) and the range would be [0,∞)
$47. 33 for the final answer
Answer:
A= 45 degrees
Step-by-step explanation:
aight so basic info here: all triangles are equal to 180 degrees knowing this we gotta make equation
80+7x-4+8x-1=180
combine like terms
75+15x=180
15x= 105
x= 7
now plug it back in
7(7)-4
49-4
45
6.22222222222
2 over 3 to the power of 2 + 5 × 2 − 4=6.22222222222
