The solid shown was formed by cutting a right circular cylinder in half. If the base has a radius of 6 cm and the height is 10 cm, what is the total surface area, in terms of $\pi$, of the solid?
Area of top hemicircle + bottom semicircle = πr2 = π*62 = 36π
Area of side rectangle = lh = 2*6(length is 2*radius)*10 = 120m2
Area of outer curve = lh = π*6(1/2 circumference is length)*10 = 60π
Total surface area = 96π + 120
Hope this helps!
Edit: I cannot English anyway so...
“Simi” is used if the root word is Latin based; “Himi” is used if the word is Greek based.
“Dimi” is used if the word came in to use when the English were adopting words from the French.
One of Chimp Stuart’s (Lancelot Link’s professional translator) favorite words covers all the bases: hemidemisemiquaver—a 64th note.
