Answer:
A. 68 units2
Step-by-step explanation:
First of all to solve this problem we have to know the formula to calculate the surface area of the cone
A = area
r = radius = 4
L = 13
π = pi
A = π*r² + π*L*r
we replace with the known values
A = π * (4u)² + π * 13u * 4u
A = 16π u² + 52π u²
A = 68π u²
The surface area of the cone is 68π u²
Answer:
11/25
Step-by-step explanation:
Answer: 23,5%
Step-by-step explanation:
% = 
= 0,235 = 23,5%
A divide by sin A =b divide by sinB
3 divide by sin 20= AB divide by sin 90
AB=sin 90 times 3 divide by sin 20
=8.77 cm
Answer:
543,800
Step-by-step explanation:
You have to look to the right of the hundreds place. If its 4 or below, go down if its 5 or up, the number goes up. Hope this helps! :D
