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 = 
BA = (π)(9.5)²
BA = 90.25 π cm²
3) Surface Area of Cone = 
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
Answer:

Step-by-step explanation:
Answer:
2,122.64 square units or
units squared
Step-by-step explanation:
The surface area of a sphere can be found using the formula
. Since the radius is 13 units, substitute r=13.

Without multiplying 3.14 for
, the answer is

Answer:15
Step-by-step explanation:
203---- 100%
x-----148%
x=203*148/100=203*1.48=300.44
