Answer:

314 \frac{2}{7} cm^{2}

Surface area of sphere= 4πr², where r is the radius of the sphere.

Given that the diameter is 10cm,

2(radius)= 10cm

radius= 10 ÷2

radius= 5cm

Surface area of sphere

= 4( \frac{22}{7} )( {5}^{2} ) \\  = 314 \frac{2}{7} cm^{2}

Semmy [17]

Answer:

Amount required = 2,217,600

Step-by-step explanation:

Dimensions of the rooms are as follows;

Room 1; 9 feet × 12 feet

Room 2; 14 ft × 16 ft

Room 3; 12 ft × 14 ft

Perimeter of rooms;

P1 = 2(9 + 12) = 42 ft

P2 = 2(14 + 16) = 60 ft

P3 = 2(12 + 14) = 52 ft

Total perimeter; P = 42 + 60 + 52 = 154 ft

Height is 90 ft.

Thus, total area is;

A = 154 × 90

A = 13860 ft²

Rate of painting is 160 per Sq.ft.

Thus amount to paint entire area = 160 × 13860 = 2217600
