The circumference of the quarter circle is one-fourth the circumference of a full circle with radius 8cm, so:
C = 1/4(2πr)
C = 1/4(2π8)
C = π4
The circumference of the base of the cone is equal to the circumference of the quarter circle, so:
C = π4 = 2πr
r = π/8
Therefore, the base radius of the cone is π/8 cm.
C = 1/4(2πr)
C = 1/4(2π8)
C = π4
The circumference of the base of the cone is equal to the circumference of the quarter circle, so:
C = π4 = 2πr
r = π/8
Therefore, the base radius of the cone is π/8 cm.
