Answer:
True.
Here, radius of the sphere = radius of the cylinder = r
Diameter of the sphere = height of the cylinder = 2r
Surface area of the sphere = 4πr2
Curved surface area of the cylinder = 2πr (2r) = 4πr2
Step-by-step explanation:
Answer:
10 5/12
When the numerator is larger than the denominator, we take groups of whole fractions (The numerator and denominator are equal) and add 1 to the whole number for each group. Whatever remains when we no longer have the numerator larger than the denominator is left as a fraction.
Step-by-step explanation:
6 3/4 + 3 2/3
We need to get a common denominator
The common denominator is 12
We need to rename the fractional parts to out of 12
6 3/4 = 6 3/4*3/3 = 6 9/12
3 2/3 = 3 2/3*4/4 = 3 8/12
6 9/12+ 3 8/12
9 17/12
But the numerator is larger than the denominator
We take 12/12 from the fraction and add it to the whole number
9 17/12-12/12 +1
9+1 5/12
10 5/12
3 units down would be subtracting 3 from the Y values and 4 units left would be subtracting 4 from the X values
Point A is at (2,-1)
The new point would be at (2-4, -1 -3) = (-2,-4)
Point B is at (1,-4)
The new point would be at (1-4, -4 -3) = (-3,-7)
Point C is at (3,-5)
The new point would be at (3-4, -5-3) = (-1,-8)
Point D is at (5,-3)
The new point would be (5-4, -3-3) = (1,-6)
So the new location would be:
A' (-2,-4)
B' (-3,-7)
C' (-1,-8)
D' (1,-6)
.8 it represents .80 cents. rather than .08 which would represent 8 pennies
