Half circle plus quarter circle is equal to three-fourths of a circle. Three-fourths of a circle plus one eighth of a circle is seven-eighths. You still need one more eighth to complete the circle.
One half of a circle plus two tenths of a circle equals 0.5 + 0.2 = 0.7 of a circle. To convert this into a percentage, multiply by 100: 0.7 * 100 = 70%. Therefore, one half of a circle plus two tenths of a circle is 70% of a whole circle.
