Radius is 3.5
diameter is 7
X/24 = 25/100
100x = 600
100x/100 = 600/100
x = 6
6 students failed the test
The number "R" could be "A" and "D" because the range is 14 it cant be "B" or "C"
Step-by-step explanation:
4. b 612 (72/100) x 850)
5. c. 275 (33/100) x 835
6. b. 39% (3.24 - 2.85) x100%)
S.A = (2×area of base) + area of lateral faces
Area of lateral faces = area of base × height
Area of lateral faces = 19×4×8=608
S.A = (2×19×4)+608
=760
