Question

NEED HELP WITH ALL THIS ASAP​

Answer 1

First question:

• radius(r)= 29 yd

• Circumference = 58 π or 182.21 yd

• Area = 841π or 2642.08 yd².

Second question:

• Perimeter = 33 cm

Thirfd question:

• Area = 174 mm²

Explanation:

For 1st Question:

Given:

Diameter(d)= 58 yd

Since radius is half of diameter, So

radius(r)= 58/2 = 29 yd

Now,

Circumference of the circle = 2πr

= 2*π*29

=58 π or 182.21 yd

Again,

Area of the circle = πr²

= π*29²

= 841π or 2642.08 yd²

Therefore, Circumference = 58 π or 182.21 yd and Area = 841π or 2642.08 yd².

For 2nd Question:

Perimeter = Sum of all sides

= 3cm + 12 cm + 5cm + (9-3) cm + (12-5) cm

= 33 cm

Therefore, Perimeter = 33 cm

For 3rd Question:

To find the area, let's divide the given figure in A and B rectangle. Attach ment.

We know that,

Area of rectangle = length * breadth

Let's find area separately:

Area of A rectangle = AB*BC

= 15*6

= 90 mm²

Area of B rectangle = DF * FE

= 14*(15-9)

= 84 mm²

Total area = Area of A rectangle + Area of B rectangle

= 90 mm² + 84 mm²

= 174 mm²

Therefore, Area = 174 mm²
