The average of 6, 15 and m is (6 + 15 + m) / 3 = (21 + m)/3 = 7 + m/3
0.5*(15+12)*4 = 54 sq m
Curved surface area = pi*2*15 = 94 square meters (to nearest integer)
The base is 21m because area is 0.5*20*21 = 210 square m
The area of the floor: 25 m length and 15 m width is 375 m2.
The average of 6, 15 and m is (6 + 15 + m) / 3 = (21 + m)/3 = 7 + m/3
If the area of the triangle is 210 square m and its height is 20 m Then its base is: 21 m Check: 0.5*21*20 = 210 square m
area of square, formula:A=a*a or a^2plug the knownA=21*21A= 441 m^2 ;))
21 m 6 cm
Total surface area of cone = (pi*radius*slant height) + (pi*radius2) Area = (pi*12*21) + (pi*122) = 1244.070691 or about 1244 square m
Area = Length * Width = 5 m * 3 m = 15 square metres
The lateral area of a right circular cone with a base diameter of 4 m and a slant height of 15 m is: 94.25 m2
Perimeter= 2(l+b) =2*39 =78m = Area =l*b = =24*15 =360m
30 × 15 = 450 square metres (450m2).
m-15=3 m-15+15=3+15 m=3+15 m=18
0.5*(15+12)*4 = 54 sq m
This is simple 100 X 500 = 50,000. The area is 50,000 square meters
