Surface area of a cone = π{rs+r²}<br /> =πr{s+r}<br />part 1:if π is 6 units and s is 4 units then r would be 3.14 ×6 {4+6}<br /><br />part 2: area of a cone = 3.14 ×6×10<br /> =31.4×6<br /> = 188.4 units²<br />the surface area = 188.4 <br />units²<br /> hope i helped
X+60 + 70 = 180 (straight line)
x+130=180
x= 180 -130
x=50
