What is the total surface area of the cone?

A.) 224π cm^2
B.) 147π cm^2
C.) 175π cm^2
D.) 273π cm^2

Total surface area of the cone is 224π cm²

Step-by-step explanation:

l² = h² + r² = 24² + 7² = 576 + 49 = 625

∴ l = √625 = 25 cm

Total surface area of the cone = πrl + πr² = πr(l + r)

                                                  = π × 7 (25 + 7)

                                                  = π × 7 × 32

                                                  = 224π cm²

d) the triangle is a right triangle 60 squared +144 squared= 156 squared

step-by-step explanation:

156 squared is the hypothenuse

so 156= c

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
