Answer:
6π units
Step-by-step explanation:
The circumference (C) of a circle is calculated as
C = 2πr ( r is the radius )
Since we only require one half of the circumference, then
0.5C = πr
given diameter = 12 then r = 12 ÷ 2 = 6, then
arc length = π × 6 = 6π units
Answer:
Step-by-step explanation:
The figure is made up of a square with side 4 cm and 3 semicircles of radius 2 cm.
A = area of square + area of 3 semicircles
A = (4 cm)^2 + 3 * (1/2) pi * (2 cm)^2
A = 16 cm^2 + (1/2) 12pi cm^2
A = (6pi + 16) cm^2
7/10 is the fraction for 0.7
