Answer:
18
Step-by-step explanation:
because 3x6 = 18
Answer:
s=6
Step-by-step explanation:
slope(m) = (y2-y1)/(x2-x1)
or, -3 = (-6+9)/(5-s)
or, -3(5-s) = 3
or, -15+3s = 3
or, 3s = 18
so, s = 6
Because this is an isosceles triangle, 3x = x + 10. Thus, 2x + 10 and x = 5.
With x=5, MN has the length 5+10, or 15.
Answer:
Option A = 113.04in^2
Step-by-step explanation:
Question: What is the total surface area of the cylinder? If the radius is 2in and height is 7in.
A) 113.04 in.2
B) 100.48 in.2
C) 131.88 in.2
D) 69.08 in.2
Solution:
Total surface area of a cylinder = 2πr^2 + 2πrh
r = radius = 2in
h = height = 7in
Let π = 3.14
Total surface area of the cylinder =
2×π×2^2 + 2×π×2×7
= 8π + π×28
= 8×3.14 + 3.14×28
Total surface area of the cylinder = 113.04in^2
=113.04in^2 (option A)
