Explanation:
Answer:
The impact and mitigation techniques are the following:
Explanation:
1. Earthquake: Earthquake cause severe damage to the building and infrastructure that leads to high deaths of people and losses to property. It can be mitigate by making more strong infrastructure and avoid making building in those region where earthquakes occurs.
2. Landslides: It also cause high damage to the soil as well as to the people by killing them. Vegetative cover and growing of trees on the edges of lands can reduce its frequency.
3. Tsunamis: It causes severe damage to the coastal regions and cause damage to the property as well as to the people. The damages can be reduced by making strong wall in the coastal regions. Vertical evacuation to existing natural high ground, tsunami-resistant structures are also mitigating techniques.
4. Floods: It causes great damages to both property, land and people. It can be reduces by making dams as well as reduce pollution that cause global warming.
5. Droughts: It can reduce the crop productivity of an area. Crop rotation. Contoured row crops, Terracing and Tillage practices are the mitigating techniques used for drought.
Answer:
The area of the sector is 33
.
Explanation:
A sector is a part of a circle that is formed by two radii (which forms a central angle), and an arc. The area of a sector (in radians) is given by:
= (θ ÷ 
) × 
where: θ is the central angle of the sector and r is the radius of the circle of which the sector is a part.
Area of a circle = . But the area of the circles was given to be 36.
Area of the sector = (θ ÷ ) × area of the circle
= (θ ÷ ) ×36
θ has been given to be 
.
Therefore;
Area of the sector = ( ÷ ) ×36
= 
× 36
= 11 × 3
= 33
The area of the sector is 33.
