The new cube will have 7 surfaces: 4 equal square sides, 2 square surface with a hole, and one hole surface.
Area (A1) of 4 square surfaces = 4*L*W = 4*4*4 = 64 cm^2
Area (A2) of the two surfaces wit a hole = 2(L*W - 2πd^2/4) = 2(4*4-π*2^2/4) = 25.72 cm^2
Area (A3) of the hole = πD*W = π*2*4 = 25.13 cm^2
Total surface area, A = A1+A2+A3 = 64+25.72+25.13 = 114.85 cm^2
Answer:
122.5 cm²
Step-by-step explanation:
a = 21cm
b = 14cm
h = 7cm
Area of given figure(trapezium) = 
= 21 + 14/ 2 * 7
= 35/2 * 7
= 17.5 * 7
= 122.5 cm²
Answer:
6/0
Step-by-step explanation:
Step 1: Label your x and y's
(0,-11) (0, 5)
x1 y1 x2 y2
Step 2: Plug in your x1, x2, y1, and y2 into the slope formula
The slope formula is y1 -y2/ x1 - x2
-5-(-11)/ 0 = 6/0
Undefined
