Step-by-step explanation:

Let's check

Let radius be x

Circumference:-

➜2πr

➜2πx

New radius=3x

New Circumference:-

➜2πr

➜2π3x

➜6πx

Taking ratio:-

➜2πx/6πx

➜1/3

➜1:3

If we quadruple the radius Circumference will also be quadrupled.

Height = 8 cm

Step-by-step explanation:

Volume of cylinder = π×r²×h

288π = π × 36 × h

Find major of 1 in the diagram.

34kurt

Answer:

85° (C).

Step-by-step explanation:

35° should go over to the other side of the line:

180 - 35 = 145°

Find angle 1:

145 + 130 + angle 1 = 360°

360° = 275° + angle 1

angle 1 = 360 - 275

angle 1 = 85°

85° which is C is the answer.
