It is C because 4 pi r^2 is the surface area equation. 4 times 6 squared= 144. 144pi = surface area.
Step-by-step explanation:
18.029= (1×10)+(8×1)+(2×1100)+(9×1100)
Make bottom number same
4/13 times 10/10=40/130
3/10 times 13/13=39/130
between 40/130 and 39/130
hmm
we can doulbe both (time 2/2 each)
80/260 and 78/260
a ratioal number between is 79/260
Answer:
D) L = 315 cm2 ; S = 399.9 cm2
Step-by-step explanation:
Lateral area;
3 × (½)(14)(15)
315 cm²
Surface area:
315 + (½)(14)(14)sin(60)
399.8704896 cm²
