Answer:
Step-by-step explanation:
Surface area=2*(lb+lh+bh)
=2*( 5*4 + 5*1.5 + 4*1.5)
=2* ( 20 + 7.5 + 6.0)
= 2 * 33.50
= 67.0 = 67 square units
Answer:
L = length of arc , R = radius
radian angle = L / R
L = R* radian angle
L = R * 1/3
L = R/3 #1
Area of sector = 1/2 L*R
By substitution using #1
Area of sector = 1/2 * R/3 * R
9 = R^2 /6
R^2= 6*9
R^2= 36
R =✓36
R = 6
