Simplifying makes a algebric expression easily understandable and solvable.
Part A:
The circumference of the circle is 197.92.
Explanation:
The formula for circumference of a circle is C=2 πr. If you insert the numbers, it would be C=2 x 3.14 x 31.5. Hence, the answer is 197.92.
Part B:
The area is 3117.25 square cm.
Explanation:
The formula for area of a circle is A= πr ². Inserting the numbers, it is A=3.14 x 31.5 ². Therefore the answer is 3117.25 cm ².
Answer:
A
Step-by-step explanation:
I hope I am right.....
Ok, so the equation of a line that passe through the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)
given slope (or gradient) of 2 and point (1,4)
y-4=2(x-1)
you can get several forms
point slope: y-y1=m(x-x1)
slope intercept: y=mx+b
standard form: ax+by=c
so, sloving for each
y-4=2(x-1)
y-4=2x-2
y=2x+2, that's slope intercept
2x-y=-2, tat's standard form
Answer:
Area = 120
Step-by-step explanation:
Triangle formula:
(b x h)
Given:
(10 x 24)
Multiply 10 and 24 to get 240.
10 x 24 = 240
Divide 240 and 2 to get 120.
240 ÷ 2 = 120
So answer is 120.
