Can anyone help me with this question please?

Answers

Answer:

√34 yards

Step-by-step explanation:

Use the Pythagorean Theorem to find what c is. The Pythagorean Theorem is a^2+b^2=c^2. In this case, a is equal to 3 and b is equal to 5. This means that the equation will be 3^2+5^2=c^2. Simplify to get 9+25=c^2. Add 9 and 25 to get 34. 34=c^2. You want c to be equal to one so you have to divide both sides by the power of 2. This will make it c=√34 yards.

Answers

Answer: c=35

D=90

E=55

Step-by-step explanation:

Since d is a right angle it is 90. Take 90 and subtract it from 180 to get 90.Set them equal to 90 so 3x+11+5x+15=90

Simplify

8x+26=90

8x=64

X=8

Now take x and plug it in for each equation

3(8)+11=35

5(8)+15=55

So measured of c is 35

Measure of e is 55

And d is 90

A rectangle has an area of 39.6m2.
One of the sides is 2.2m in length.
Work out the perimeter of the rectangle.

Answers

the perimeter is 40.4m because 39.6/2.2=18 and since there are 4 sides, add 18 twice as the longer sides. 2.2 is the length of the two shorter sides so you add 18+18+2.2+2.2 to get 40.4m.

What is the perimeter of a half circle with a radius 22cm .round your answer to the nearest whole number

Answers

Answer:

113.115 cm

Step-by-step explanation:

Formula:

C = 2πr

Given:

Radius: 22 cm

Diameter: 44 cm

The perimeter of a semicircle is the sum of half of the circumference of the circle and its diameter.

Simply plug in your numbers to find the circumference first.

C = 2π(22)

C = 44π cm or 138.23 cm

Then, divide the circumference in half, and add your diameter.

Perimeter = (44π/2) + 44 = 113.115 cm
