Calculate the area of this trapezium. 7.9 cm 6.2 cm 10.8 cm

Mathematics
1 answer:
cestrela7 [59]3 years ago
5 0

Answer:

A = 57.97 cm²

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = \frac{1}{2} h (a + b)

where h is the perpendicular height and a, b the parallel bases

Here h = 6.2, a = 10.8 and b = 7.9, thus

A = \frac{1}{2} × 6.2 × (10.8 + 7.9) = 3.1 × 18.7 = 57.97 cm²

What is the equation of a line parallel to the line y = 4x + 7 and passes through the point (3, 0)?
KATRIN_1 [288]
Two lines to be parallel their slopes have to be equal. 

so m1 = m = 4


y = mx + b ( Slope intercept form)


y = 4x + b

(3,0) is on the line:

0 = 12 + b

b = -12

y = 4x - 12

What is the diameter of circle T?
Ratling [72]

Answer:

Diameter = 16

Step-by-step explanation:

Given

\theta = 72

Sector = \frac{64}{5}\pi

Required

Calculate the diameter

The area of a sector is:

Area = \frac{\theta}{360} * \pi r^2

Substitute values for Area and \theta

\frac{64}{5}\pi = \frac{72}{360} * \pi r^2

Divide both sides by \pi

\frac{64}{5} = \frac{72}{360} * r^2

Make r^2 the subject

\frac{64*360}{5*72} = r^2

\frac{64*360}{360} = r^2

64 = r^2

Take positive square roots of both sides

\sqrt{64} = r

8 = r

r = 8

The diameter is then calculated as:

Diameter = 2r

Diameter = 2*8

Diameter = 16
