Use Phythagoras Theorem!!

the length pf a rectangle is 50 cm and its diagonal is 51 cm. work out the area of the rectangle, to the nearest square centimetre.​

Answers

Answer 1

a² + b² = c²

50² + 51² = c²

2500 + 2601 = c²

5101 = c²

√5101 ≈ 71.42 cm.

Answer 2

Answer: Area of the rectangle = 102.5 cm²  Round to 103 cm²

Step-by-step explanation:

The diagonal is the hypotenuse, c So subtract the square on the base (length) to find the altitude (height).

a² + b² = c²

a² + 50² = 51²

a² = 51² - 50²

a² = 2601 -2500

a² = 101  take the square root of both sides

a = √101

a = 10.04987562  Round to 10.05

Area = LW

Area = 50 × 10.05

Area = 102.5 cm²  Round to 103 cm²

Find the height of a cone with a diameter of 12 m whose volume is 226 m^3.
Use 3.14 for it and round your answer to the nearest meter.

A. 5 m
B. 2 m
C. 19 m
D. 6 m

Answers

Answer:

D. 6m

Step-by-step explanation:

Ap3x

The height of a cone with a diameter of 12 m whose volume is 226 m^3 is 6 m

What is the cone of a height?

The height of a cone is calculated using the formula:

h = 3V/πr 2

Where h = height of the cone

V = volume of the cone

r = Radius of the cone

But note that radius, r = diameter divided by 2

r = 12 ÷ 2 = 6m

Volume = 226 m^3

How to calculate the height of  a cone

Substitute the values into the formula

h = 3 × 226 ÷ 3.14 × 6 × 6

h = 678 ÷ 113. 04

h = 6m

Therefore, the height of a cone with a diameter of 12 m whose volume is 226 m^3 is 6m

About 7/10 of the surface of the earth is covered with water. Express this as an equivalent fraction with 100 as the denominator. Fraction with 100 as denominators are known as per cent 50/100 means 50 per cent. So what percentage of the earth's surface is covered with water? What percentage covered with land

Answers

Answer:

70/100

Step-by-step explanation:

Surface of the earth covered with water = 7/10

Equivalent fraction of 7/10 with 100 as the denominator = 70/100

This means 70% of the earth surface is covered with water

Percentage covered with land = Total percentage - percentage covered with water

= 100/100 - 70/100

= 100-70/100

= 30/100

Percentage covered with land = 30%
