True or False The area of a circle of radius 14 units is equal to the surface area of a sphere radius 7 units

Answers

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 = $\pi r^2$

given : r = 14 units

So, Area of circle = $\pi (14)^2$

Simplify, we have,

Area of circle = $196\pi$ units²

Now,

Area of sphere = $4\pi r^2$

given : r = 7 units

So, Area of sphere = $4\pi (7)^2$

Simplify, we have,

Area of sphere = $196\pi$ 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.

The answer is true. The area of a circle of radius 14 units is equal to the surface area of a sphere radius 7 units

Which one is smaller; 0.0175, 0.65, or 0.876

Answers

0.0175, 0.65, 0.876

The smallest among these is 0.0175

after the decimal point, we see that in 0.0175 the tenth value is 0
in 0.65 the tenth value is 6
and in 0.876 the tenth value is 8

So from smallest to biggest(if needed)

0.0175, 0.65, 0.876
