_________A parallelogram has an area of 288 square centimeters and a height of 12 centimeters.
What is the length of the base of the parallelogram?
____cm
Answer:
A = 21.4 m²
Step-by-step explanation:
A = 2×1.7×2/2 + 2×2×3 + 2×3
= 3.4 + 12 + 6
= 21.4 m²
Answer:
Step-by-step explanation:
First write it the shorter way. Leave out the middle term. What you have is the difference of squares.
a^2 - b^2 = (a + b)(a - b)
4x^2 - 9
(2x - 3)(2x + 3)
The answer is B
Answer:
True
Step-by-step explanation:
Given: Statement :"The area of a circle of radius 14 units is equal to the surface area of a sphere radius 7 units"
We have to choose whether the given statement s true or false.
Consider the given statement.
The area of a circle of radius 14 units is equal to the surface area of a sphere radius 7 units
We first find the area of circle with 14 units radius and area of a sphere with 7 units radius and compare the two values.
We know,
Area of circle =
given : r = 14 units
So, Area of circle =
Simplify, we have,
Area of circle = units²
Now,
Area of sphere =
given : r = 7 units
So, Area of sphere =
Simplify, we have,
Area of sphere = units²
Since, Area of circle with radius 14 units is equal to the area of sphere with radius 7 units.
Thus, The given statement is true.
