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

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
