The height of the cylinder is 7 centimeters. The volume and radius of the cylinder were used to find the height using the formula for the volume of a cylinder.
The formula for the volume of a cylinder is given by V = πr²h, where r is the radius and h is the height.
Substituting the given values, we get:
112 = π(4²)h
Simplifying:
112 = 16πh
Dividing both sides by 16π:
h = 112 / (16π)
Using a calculator to evaluate this expression, we get:
h ≈ 0.55 cm
Therefore, the height of the cylinder is approximately 0.55 centimeters.

B. 49 cm 2
c. 96 cm 2
D. 24.5 cm 2
Answer:
Option A. 191cm²
The area of the circle is 191 cm²
Step-by-step explanation:
To solve this problem we need to use the area formula of a circle:
a = area
r = radius = 7.8cm
π = 3.14
a = π * r²
we replace with the known values
a = 3.14 * (7.8cm)²
a = 3.14 * 60.84cm²
a = 191.03 cm²
The area of the circle is 191.03 cm²

A is correct answer... 100% sure
Answer:
m∡2 = 64°
Step-by-step explanation:
By definition of vertical angles, the angles opposite of each other are equal each other.
∴ IF ∡1 and ∡2 are vertical angles, AND m∡1 = 64°, THEN m∡2 = 64°. (CPCTC - Definition of Vertical Angles).
~
Vertical angles are equal. Therefore, if ∡1 is 64°, then ∡2 is also 64°.
In mathematics, vertical angles are a pair of non-adjacent angles formed when two lines intersect. By definition, vertical angles are equal in measure.
Therefore, when angle 1 (∡1 ) and angle 2 ( ∡2 ) are vertical angles, if the measure of angle 1 ( m∡1 ) equals 64° as per the question, then the measure of angle 2 (m∡2) will also equal 64°.
So, m∡2 = 64°.
