Question

Consider it this cone with a diameter of 19 cm use the drop-down menus to describe the con measurements

Answer 1

Answer:

1) Radius of the cone = 9.5 cm

2) BA = 90.25 π cm²

3) SA = 384.7 π cm²

Step-by-step explanation:

1) Radius of the cone = 9.5 cm

2) Base Area of the cone = $\pi r^2$

BA = (π)(9.5)²

BA = 90.25 π cm²

3) Surface Area of Cone = $\pi r(r+\sqrt{h^2+r^2)}$

SA = π(9.5)(9.5 + √(29.5)²+(9.5)²)

SA = 9.5π(9.5 + 31)

SA = 9.5π(40.5)

SA = 384.7 π cm²
