Question 7:
Diameter = 6.2 cm so Radius = 3.1 cm
A=πr² = 3.14 × 3.1² = 30.1754 cm² = 30.18 cm²
Question 8:
Circumference = 2πr
16π = 2πr
therefore 16 = 2r so r = 8cm
Answer:
a. yes
b. Q
c. line MP
Step-by-step explanation:
a. "Collinear" means "on the same line". The diagram shows point K on the same line with M and P, so ...
yes, M, P, and K are collinear
__
b. N, W, and U are the corners of face NUWQ, so point Q is also in that plane.
__
c. The plane MPQ includes face MPQN. The plane TVP includes face TVPM.
Line MP (or PM) is the line where these planes intersect.
Answer:
557.28
Step-by-step explanation:
since it is a refund you subtract the amount due from the amount paid to get 2700.27 - 2142.99 = 557.25
Answer:
-1
Step-by-step explanation:
Assuming problem is: x->2 (x^3 -3x^2 +3)
Since the expression is continuous at x=2,
then the limit can be found just by evaluating the expression at x=2.
2^3-3(2)^2+3
8-3(4)+3
8-12+3
-4+3
-1
