Answer:
9+ – 12(34) + 27 = 0, A= 3*
Use substitutionStep-by-step explanation:
The answer is A because the volume of a cylinder formula is 3.14 time radius squared times the height of the cylinder
Answer:
Ф = the measure of ∠BAC in radians
Step-by-step explanation:
∵ ∠BAC is a central angle
∴ The are of the sector will depended on the length of the radius <em>r </em>and the measure of the central angle <em>Ф</em>
If the measure of Ф in degrees
∴ The area of the sector = Ф°/360° (π r²)
If the measure of Ф in radians
∴ The area of the sector = 1/2 r² Ф
When to change from degree to radian you do that
Ф radian = Ф°/180 × π
∴ Ф/360 π r² = 1/2 <u>(Ф/180 π)</u> r² ⇒ ∵ underline is Ф radian
∴ Area sector = 1/2 r² Ф ⇒ Ф in radians
