The area of the sports field is 10150 square meters and the length of one lap of the track is 400 meters.

<h3>What is the area of the rectangle?</h3>

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

Area of the sports field = area of the rectangle + area of the two semicircle

Area of the sports field = 90×70 + π(70/2)²

= 6300 + (22/7)1225

= 6300 + 3850

= 10150 square meters

Length of the track = perimeter of the rectangle + circumference of the

                                   two-semi circle

= 90 + 90 + 2π(70/2)

= 180 + 70(22/7)


= 180 + 220

= 400 meters

Thus, the area of the sports field is 10150 square meters and the length of one lap of the track is 400 meters.

Answer:

B. 2.2π m² : 3.2π m²

Step-by-step explanation:

Given:

Slant height (l) = 2.2 m

Diameter (d) = 2 m

Radius (r) = ½(2) = 1 m

Required:

Lateral area and surface area

Solution:

✔️Formula for lateral area of a cone = πrl

Plug in the values

Lateral area of the cone = π*1*2.2

Lateral area = 2.2π m²

✔️ Formula for surface area of a cone = πr(l + r)

Plug in the values

Surface area of the cone = π*1(2.2 + 1)

Surface area = π(3.2)

Surface area = 3.2π m²

The answer would therefore be:

2.2π m² : 3.2π m²

How to solve 4+|7-m|=5
notka56 [123]
When
|a|=b
assume
a=b and -a=b
so

4+|7-m|=5
minus 4 from both sides
|7-m|=1
assume
7-m=1 and
-(7-m)=1

7-m=1
minus 7 both sidees
-m=-6
times -1 both sides
m=6

-(7-m)=1
distribute
-7+m=1
add 7 to both sides
m=8

m=6 and 8
