Which reflection will produce an image of δrst with a vertex at (2, –3)? a reflection of δrst across the x-axis a reflection of δrst across the y-axis a reflection of δrst across the line y = x a reflection of δrst across the line y = –x

the answer on e2020 is D "reflection of RST across the line Y=--x

D. a reflection of ΔRST across the line y = –x

is there answer choices?

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
