Answer:
Step-by-step explanation: so the formula for the surface area of a sphere is 4*pi*radius squared. For the sphere, u have a diameter of 22. U know that the radius is 11 cuz radius is half of diameter. So u plug in that 11 into the formula and you have the answer! I hope this helps ;)
Given:
Consider a rhombus.
To find:
Which of the given statements about a rhombus is not true?
Solution:
Properties of a Rhombus:
1. It is a quadrilateral which is a special case of a parallelogram.
2. It has four equal sides.
3. It has two sets of parallel sides.
4. Opposite angles are equal.
5. Diagonals are perpendicular bisectors.
Since a rhombus doesn't has four right angles, therefore the last statement in the given options is not true about the rhombus.
Hence, the correct option is D.
The slope is
2-1
m = rise / run = ------- = -1/2
1-3
Answer:
Step-by-step explanation:
formula
d = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )
Givens
x2 = 2
x1 = - 7
y2 = -6
y1 = - 6
Solution
d = sqrt( (2 - - 7)^2 + (-6 - - 6)^2 )
d = sqrt( 9^2 + (-6 + 6)^2 )
d = sqrt(9)^2
d = 9
Bisected means half, so just divide by 2:
15 degrees
