Answer:

Problem 1: 12.56

Problem 2: 20.94

Step-by-step explanation:

Problem One (left)

Givens

r = 16

Theta = 45 degrees

pi = 3.14

Formula

Length = theta/360 * pi * 2*r

Substitute ans Solution

Length = 45/360 * pi *2*16      Substitute

Length = 0.125 * 3.14 * 32        Combine 45 / 360 = 0.125

Length = 12.56 <<<< Answer

Problem Two

Theta = 120

pi = 3.14

r = 10

Substitute and Solution

Length = 120/360  * pi * 2*r

Length = 1/3 * 3.14 * 2 * 10

Length = 1/3 * 3.14 *20

Length = 20.94

Eduardwww [97]

Answer:

2cm

Step-by-step explanation:

The volume of water displaced by the rod is

v = πr^2 h = π * 3^2 * 8 = 72π cm^3

The drop in water level is the rod volume divided by the cross-section area of the tin, or

72π/(π*6^2) = 2 cm

Two angles, Angle A and Angle B are supplementary to one another. If the measure of B is 30 degrees more than the measure of A,
iVinArrow [24]

Answer:

m<A = 75 and m<B = 105.

Step-by-step explanation:

To find the two angles, we first take 180 (because supplementary angles are two angles that add up to 180) and we divide it by 2 to get 90. Then we take 30 degrees and divide that by 2 to get 15. You add 15 degrees to measure B and subtract 15 degrees to measure A. So then you get m<A = 90 - 15 = 75 and m<B = 90 + 15 = 105.
