Pls help me pls

Step-by-step explanation:

Volume of the cylinder

Givens

h = 30-10 = 20

d = 20

r = d/2 = 20/2 = 10

Formula

V = pi r^2 h

Solution

V = 3.14 * 10^2 * 20

V = 6280

Volume of the cone

Givens

h = 10

d = 20

r = d/2 = 20 / 2 = 10

Formula

V = 1/3 pi r^2 h

V = 1/3 * 3.14 * 10^2 * 10

V = 1046

Total Volume

V_cone + V cylinder

V = 1046 + 6280

V = 7326.7

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
