The surface are of the right cone is 176 sq.units. Option A) is the correct answer.
<u>Step-by-step explanation</u>:
<u>step 1</u> :
Radius of the cone, <em>r = 4</em>
Height or length of the cone,<em> h = 10</em>
<u>step 2</u> :
Total surface area of right cone = πrh + πr^2
= (π
4
10) + ( π
4^2)
= 40π + 16π
= 56 π = 56
3.14
= 176 sq.units
