1. round to nearest whole number.
a. 165 m^2
b. 176 m^2
c. 330 m^2
d. 351 m^2

2. Round to the nearest whole number.
a. 221 cm^2
b. 240 cm^2
c. 304 cm^2
d. 620 cm^2

Answer 1

your answer would be 165

Answer 2

Surface Area of a Cone Formula:
SA=π*r(r+h^2+r^2)
Surface Area of a Square Pyramid Formula:
SA=a^2+2a √a^2/4+h^2
Lateral Area of a Square Pyramid Formula:
AL=a√a^2+4h^2
Lateral Area of a Cone Formula:
AL=π*r*h^2+r^2
