b) The side of a cube is 4cm.Find its volume.
c) Name the longest chord of a circle.
d) The radius of a circle is 8cm. What is its diameter?​

Answer 1

Answer:

the radius of a circle is 8 cm.

Answer 2

• Measure of Right angle triangle =90 °

• Volume of cube = L³

=(4)³

Volume of cube = 64 cm³

• longest chord of circle is diameter

• r (radius) = d(diameter) / 2

d ( diameter ) = r × 2

d ( diameter ) = 8 × 2

d ( diameter ) of circle = 16 cm
