Brenda has a circular garden of radius 21 m . She ran round the garden twice .what distance did she cover

Brenda ran 263.76 metres.

Step-by-step explanation:

The circumference of a circle is two times pi times its radius. Brenda rand that twice, so we need:

2 × 2πr

= 4πr

= 4 × 3.14 × 21m

= 263.73m

you would need to know all the numbers that are on there

step-by-step explanation:

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
