Answer:
P = 15.42 cm
Step-by-step explanation:
Perimeter of circle = (πD/2)+D
Where D = 6 cm
P =( (3.14)(6)/2) + 6
P = (3.14)(3)+6
P = 9.4 + 6
P = 15.4 cm
Answer:

Step-by-step explanation:
A line is perpendicular to another if its slope is the negative reciprocal of the other.
Your lines are in slope intercept form here, y=mx+b, where m is the slope. We can see the given line has slope
. The negative reciprocal of that is
, which is the slope of the third answer choice.
Answer:
1) a right triangle
Step-by-step explanation:
One of the caractheristics of a right triangle, the one in which the sum of the two sides squared is the hypotenuse squared(Pytagorean Theorem), is also the the altitudes of a triangle meet at one of the triangle’s vertices. So 1) is the answer to this question.
Answer:
total 20 squares in matrix of size 4×3
Step-by-step explanation:
in square of size 1×1
six squares of size 2×2
2 squares of size 3×3
The formula for circumference is pi(diameter) or 2 x pi x radius. So you have the diameter which is 4.25. Next step you need to do is multiply it with pi which is equal to 3.14. Your equation would be C= 3.14 x 4.25.
