Try a tape measure and a calculator to measure surface area.
Area = pi*152 square mm
A circle is fully defined by just one measure - its radius or diameter or circumference of area. I am sure there cannot be a circle with two measures as in the question!
The circle around home plate generally measures 26 feet in diameter. This area is referred to as the home plate area.
Diameter = 30cm so radius = 15 cm. Then Area = pi*r2 = 706.9 cm2

For a circle where sector measures 10 degrees and the diameter of the circle is 12: Sector area = 3.142 square units.
Area of the circle: pi*92.52 = 26880 square mm as a whole number
Try a tape measure and a calculator to measure surface area.

A rain gauge is a weather instrument that measures precipitation in inches, typically used to measure rainfall.
A circle is fully defined by just one measure - its radius or diameter or circumference of area. I am sure there cannot be a circle with two measures as in the question!
A seismograph is an instrument used to measure movement of earthquake. It measures the seismic waves of that area.
The circle around home plate generally measures 26 feet in diameter. This area is referred to as the home plate area.
This instrument is a balance.
An instrument that measures heat and cold is called a thermometer.
A calorimeter measures heat. In contrast, a thermometer measures temperature.A thermometer bolometer - an instrument that measures heat radiation; extremely sensitive calorimeter - a measuring instrument that determines quantities of heatHeat is measured with a ThermometerThermometerThermometer or calorimeterThermometerthermometerHeat is measured with a thermometer.
