Answer:
Step-by-step explanation:
Given:
Radius(r)= 25 cm = 25/100= 0.25 m
[1 cm = 1/100m]
Height (h)= 3.5 m
Curved surface area of Cylinder= 2πrh
= 2× (22/7) × 0.25 × 3.5
= 2× 22× 0.25 × 0.5
= 2× 0.5 ×22× 0.25
= 1 ×22× 0.25
= 5.5 m²
Curved surface area of 1 Cylindrical column= 5.5 m²
Curved surface area of 10 Cylindrical column= 5.5 × 10= 55 m²
Rate for painting 1 m² of the cylindrical column = ₹ 15.50
Cost of painting 10 cylindrical columns= 55 × 15.50 = ₹ 852.5.

Answer:
B and A
Step-by-step explanation:
the triangles are congruent by AAA
all angles in a triangle add up to 180º
1. 180-27-115 = 38º
2. 180-20-135 = 25º
3. 180-55-47 = 78º
4. 180-27-125 = 28º
5. 180-27-86 = 67º
6. 180-36-33 = 111º
7. 180-59-110 = 11º
angles on a straight line add to 180º or the exterior angle is equal to the sum of the opposite interior angle (i think that angle is 50 but if its not let me know)
8. 180-50 = 130º
A ray is a line with one end. It starts at a given point and goes off in a certain direction forever to infinity. The point where the ray starts is called the endpoint.
