Hint: area of a triangle=(h_b*b)/2
First plug in, the numbers and then simplify.
NVM it's 13/2
I'm pretty sure that's correct but I think one of your steps are wrong...
TOTAL SURFACE AREA OF THE CYLINDER(TSA)=462CM² CURVED SURFACE=1/3 OF TSA =1/3 X 462 =154CM² AREA OF EACH CIRCLE=(462-154)/2 =154CM² PI*R²=154 R²=49 R=7 2PI*R*H=154 H=154*7/22*7 H=3.5 VOLUME=PI*R²*H=22/7*49*35/10 VOLUME=539CM³
apply the Pythagorean Theorem
b) Hint: Find the possibilities by first finding the fraction then convert to a percent to compare.(same thingcfor (c))
a) 3 because the possibility to draw a 3 is 80% and 80%>20%
Hint: Try to factoring out (t+1)
I think it's 45...
