Answer:
Step-by-step explanation:
Acute angle
Answer:
27.72litres=27.72×1000 cm^3
(¡)Height of cylinder=27720×7/(22×21^2)=20cm
Step-by-step explanation:
(¡)First convert litres in to cm^3 take it as the volume of the cylindrical container
(¡¡)Then use V=22/7×r^2×h equation and substitute the values to V and r. Then find the value of h
#V=27.72×1000 (V= volume)
# r = 42/2=21 (r = radius)
Answer:
1. use the formula


2. use the formula

3. There is only one at 360 degrees
4. there are 6 rotational symmetries and the number of reflectional symmetries would be 6 as you can see:
Answer:
74
Step-by-step explanation:
To receive an award, student must obtain a score at or above the upper quartile, from.tye boxplot, the upper quartile is depicted by the endpoint of the box. Hence, the upper quartile of the distribution is 74. Hence only stude Ts who score 74 and above will receive an award Hence, the minimum score required is 74.
Area of Trapezoid = (1/2) * (Sum of bases) * height
Area = (1/2) * (11 + 14) * 10
= (1/2) * 25 * 10 = 5 *25 = 125
Area = 125 m²
