Volume of a Cylinder Formula: V = πr²h

V is volumer is radiush is height

Step-by-step explanation:

Step 1: Define

Radius r = 2 units

Height h = 16 units

Step 2: Find Volume

Substitute in variables [Volume of a Cylinder Formula]: V = π(2 units)²(16 units)[Volume] Evaluate exponents: V = π(4 units²)(16 units)[Volume] Multiply: V = π(64 units³)[Volume] Multiply: V = 201.062 units³[Volume] Round: V ≈ 201.06 units³

Answer from: Quest

answer

a,b, and d

explanation

a reflection angle is more than

$\pi \: radians$

but less than;

$2 \pi \: radians$

an angle that measures

$\frac{4 \pi}{3} \: radians$

is a reflex angle.(true)

an angle that measures less than

$\frac{\pi}{2}$

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

$0 \leqslant \theta \: < \frac{\pi}{2}$

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
