Answer:
B) 264 units²
Step-by-step explanation:
Figure 1:
A = 1/2BH
A = 1/2 12(4)
A = 1/2 48
A = 24
Figure 2:
24 - 4 = 20
20 x 12 = 240
Total area:
240 + 24 = 264
Answer:
66.67 in^3
Step-by-step explanation:
volume of a cylinder = nr^2h
Volume of a cone = 1/3(nr^2h)
n = 22/7
r = radius
the volume of a cone is 1/3 that of a cylinder
volume of the cone = 1/3 x (200) = 66.67 in^3
Answer:
=-18x^2+78xy-24y^2
Step-by-step explanation:
(-2x+8y)(9x-3y)
-18x^2+6xy+72yx-24y^2
-18x^2+(6xy+72xy)-24y^2
=18x^2+78xy-24y^2
