Answer:
A 1759 sq. units
Step-by-step explanation:
to find the surface area of a closed cylinder the formula is
2πr² + πdh
r = radius = 10
d = diameter = 10 + 10 = 20
2 x 3.14 x 10² + 3.14 x 20 x 18
628.3 + 1130.94 = 1759.24
ans = 1759
Step 1: Find the slope.
Step 2: Find the value of b.
Step 3: Get the y=mx+b
Answer:
2x-y-13=0
Step-by-step explanation:
Answer:
What is the question?
Step-by-step explanation:
We need to know what problem to solve with the information provided.
Answer:
Coordinates switch, and the new y-coordinate changes sign
Explanation:
We have point A with the coordinates (-1,2), when we rotate it c90º it becomes (2,1).
What happened? The coordinates switched and the x-coordinate of A (-1) became the y-coordinate of A' (1) and it changed its sign.
